ast-open.READMEThe AT&T Software Technology ast-open package from AT&T Research
contains all of the ast open source commands and libraries.  This
package is a superset of the following packages: ast-base ast-make
ast-ksh ksh ast-ast ast-dss; you won't need these if you download
ast-open.

Source Package Installation Instructions:

  (1) Do not install packages as root/super-user. Although some components may
      have setuid executables, few must be owned by root. These are best
      changed manually when the security implications are understood.
  (2) Choose a package root directory and cd to it. This will be a local work
      area for all packages.
  (3) These instructions bypass the click to download package links on the
      download site. If you already clicked, or if your system does not have
      curl(1), hurl(1), lynx(1) or wget(1) then use the alternate instructions
      for (3),(4),(5) in plan B below. Plan B installs the hurl(1)
      script which works with ksh and modern bash. The top level URL is:
        URL=http://www.research.att.com/sw/download
  (4) If the bin/package script does not exist then run:
        test -d bin || mkdir bin
        url=$URL/package
        (wget -O - $url||curl -L $url||hurl $url) > bin/package
        chmod +x bin/package
  (5) Determine the list of package names you want from the download site, then
      use the package(1) command to do the actual download:
        bin/package authorize "NAME" password "PASSWORD" \
            setup source $URL PACKAGE ...
      (Refer to the AUTHORIZATION paragraph on the main download page for
      NAME/PASSWORD details.)  This downloads the closure of the latest
      source package(s); covered and up-to-date packages are not downloaded again unless
      package force ... is specified. Package content is verified using md5sum.
      If the package root will contain only one architecture then you can install in bin and
      lib instead of arch/HOSTTYPE/bin and arch/HOSTTYPE/lib by running this
      instead:
        bin/package authorize "NAME" password "PASSWORD" \
            flat setup source $URL PACKAGE ...
      To update the same packages from the same URL run:
        bin/package setup source
  (6) Build and install; all generated files are placed under arch/HOSTTYPE
      ($INSTALLROOT), where HOSTTYPE is the output of bin/package (with no
      arguments.) name=value arguments are supported; CC and debug=1 (compile
      with -g instead of -O) are likely candidates. The output is written to
      the terminal and captured in $INSTALLROOT/lib/package/gen/make.out:
        bin/package make
  (7) List make results and interesting errors:
        bin/package results
      Run the regression tests:
        bin/package test
      List test results and errors:
        bin/package results test
  (8) The generated binaries are position independent, i.e., they do not
      contain hard-coded paths. However, commands with related files, like
      file(1) and nmake(1), require the path of the bin directory to be
      exported in PATH.
  (9) You can run the binaries directly from the package root, or you can
      install them in a public root after you are satisfied with the make and
      test actions (requires the AT&T nmake(1) command):
        bin/package flat install DIRECTORY PACKAGE
      This will install in DIRECTORY/bin and DIRECTORY/lib. If you want to
      preserve the arch/HOSTTYPE hierarchy under DIRECTORY then omit the
      flat argument. If you don't have nmake(1) then the following will do a
      flat install:
        cd $INSTALLROOT
        cp -p -r bin lib include DIRECTORY
  (10) To summarize, after the first time the download, build, and test cycle
      for the latest source release is:
        bin/package setup source
        bin/package make
        bin/package test

Source Package Installation Instructions -- Plan B:

  (3) Create the subdirectory lib/package/tgz and download all package archives
      into that directory.
  (4) If the bin/package script does not exist then manually read the INIT
      source package:
        gunzip < lib/package/tgz/INIT.YYYY-MM-DD.tgz | tar xvf -
      Note that some browsers automatically unzip downloaded without warning.
      If the gunzip fails try:
        tar xvf - lib/package/tgz/INIT.YYYY-MM-DD.tgz
      If your system does not have tar(1) or gunzip(1) then download the ratz
      source package, compile it, and manually read the INIT
      source package:
        mkdir bin
        cp lib/package/tgz/ratz.YYYY-MM-DD.c lib/package/tgz/ratz.c
        cc -o bin/ratz lib/package/tgz/ratz.c
        bin/ratz -lm < lib/package/tgz/INIT.YYYY-MM-DD.tgz
  (5) Read all unread package archive(s):
        bin/package read
      Both source and binary packages will be read by this step.

All recorded changes follow.

      now outputs an error message and returns value 126.
10-06-23  Floating point functions that happened to return integer values
      were being treated as if the function returned integers so that
      integer division could be used instead of floating point division.
10-06-22  Fixed a bug in earlier ksh93u in which an arithmetic assignment to a
      variable in the global scope would instead create a local variable if

10-05-21  A bug in which using $var inside ((...)) did not work when var was
      a hex float variable.
10-05-20 +The compile option SHOPT_EDPREDICT has been added.  When this option
      is on, as you type a line beginning with a # the following characters
      are treated as a shell pattern and cause matching lines from the
      history file to be displayed as a numbered list as you type.
      You can scroll up and down this list or you can use <ESC>nTAB
      to make this the current line (n defaults to 1 of omitted) or
      <ESC>n<cr> to execute.

      'function .sh.math.name x y z{...}' , where name is the function name
      invoked within ((...)) and x y z are long double arguments passed
      as name references.  y and z are used for functions with two and

      of the long double .sh.value variable when the function returns.
10-03-24  A bug in which integer division was mistakenly used when the
      numerator was a binary operator with the first operand floating
      point and the second integer, e.g. (.1**3)/3, has been fixed.

09-03-24 +When ksh is invoked without -p and ruid!=euid, and the shell is
      compiled without SHOPT_P_UID or ruid<SHOPT_P_UID, the shell now
      enables the -p option.  The previous version instead set the

08-12-04 +SHOPT_BGX enables background job extensions. Noted by "J" in
      the version string when enabled. (1) JOBMAX=n limits the number
      of concurrent & jobs to n; the n+1 & job will block until a
      running background job completes. (2) SIGCHLD traps are queued
      so that each completing background job gets its own trap; $! is
      set to the job pid and $? is set to the job exit status at the
      beginning of the trap. (3) sleep -s added to sleep until the time

      with a redirection and not occurring with in the while, until, if,
      select condition can be preceded by a semi-colon which will
      be ignored when showme is off.  When showme is on, any command
      preceded by a colon will be traced but not executed.
06-08-16 +As a new feature, a leading ~(N) on a pattern has no effect
      except when used for file expansion.  In this case if not
      matches are found, the pattern is replaced by nothing rather
      than itself.
06-08-11  A bug in the expansion of ${.sh.match[i]:${#.shmatch[i]}} has
      been fixed.
06-08-10 +The read builtin options -n and -N have been modified to treat

      binary (typeset -B) variable.
06-07-27 +When the here document operator << is followed directly by a #
      rather than a -, the first line of the here-document determines

      expressions.
06-06-20 +The functions isinf(), isnan(), tanhl() have been added for
      arithmetic expressions.

      selected when either /bin or /usr/bin is scanned.
06-06-04 +Added literal-next character processing for emacs/gmacs mode.
      This change is not compatible with earlier versions of ksh93
          and ksh88 when the stty lnext is control-v.  The sequence
      escape-control-v will display the shell version.
06-05-31 +Modified emacs and vi mode so that entering a TAB after a partial
      TAB completion, generates a listing of possible completions.
      After the second TAB, a number followed by a TAB will perform
      the completion with the corresponding item.

      the maximum number of precision digits.
06-05-16  Bug fixes for multibyte locales.
06-05-10  The =~ operator was added to [[...]] and  [[ string ~= ERE ]]

      (output) pipe to close before reading from (after writing to)
          it has been fixed.
06-02-28  A bug in which stopping a job created with the hist builtin command
      would create a job that could not be restarted has been fixed.

      -li and -lE to handle long long and long double types.
05-12-07 +The histexpand (-H) option has been added which allows C-shell
      style history expansions using the history character !.
05-12-07 +The multiline option was added which changes that way the edit
      modes handle lines longer than the window width.  Instead of
      horizontal scrolling, multiple lines on the screen are used.
05-12-05  The whence builtin now returns an absolute pathname when the
          command is found in the current directory.
05-11-29  A bug which caused ksh -c '[[ ! ((' to core dump rather than
      report a syntax error has been fixed.
05-11-29  A bug when reading fixed length records into typeset -b variables
      which caused a zero byte to terminate the value has been fixed.

          with a directory when a .path file was not encountered in
      the directory of the executable has been fixed.
05-09-15  A for/while loop optimizer bug in which $OPTIND was not
      correctly expanded has been fixed.
05-09-05  A bug in which a history command that invoked a history
      command could go into an infinite loop has been fixed.
05-08-31 +In the case that IFS contains to adjacent new-lines so that
      new-line is not treated as a space delimiter, only a single
      new-line is deleted at the end of a command substitution.
05-08-19 +When a tilde substitution expands to the / directory and is
      followed by a /, it is replaced by the empty string.
05-08-16  A bug in which n<&m did not synchronize m has been fixed.
05-08-16  A bug in which process substitution  ( <() and >() ) was not
      working within for and while loops has been fixed.
05-07-24  A bug in which the pattern ~(E)(foo|bar) was treated as a syntax
      error has been fixed.
05-07-24  A bug in completion with <n>=, where n was the one of the
      previous selection choices has been fixed.
05-07-21  A bug with multibyte input when no edit mode was specified which
      caused the input line to shift left/right has been fixed.
05-06-24  A race condition which could cause the exit status to get lost
      on some fast systems has been fixed.
05-06-21  A bug in which nested patterns of the form {m,n}(pat) would cause
      syntax errors has been fixed.
05-06-21  A bug in the macro expander has been fixed which could cause a
          syntax error for an expansion of the form ${x-$(...)} when
      x is set and the command substitution contained certain strings.
05-06-08 +On systems for which echo does not do System V style \ expansions,
      the -e option was added to enable these expansion.
05-06-08  A bug in which ${var op pattern} to not work when inside an
      arithmetic expression has been fixed.
05-05-23 +An extension to shell patterns that allows matching of nested
      groups while skipping over quoted strings has been added.
05-05-18  A bug in which the line number for errors was not correct for
          functions loaded from FPATH has been fixed.
05-04-18  A bug in which the exit status $? is not set when a trap triggered
      by the [[...]] command is executed has been fixed.
05-04-08 +Redirection operators can be directly preceded with {varname}
      with no intervening space, where varname is a variable name which
      allows the shell to select a file descriptor > 10 and store it
      into varname.
05-04-08 +SHOPT_CMDLIB_BLTIN=1 now includes <cmdlist.h> generated table.
05-04-07 +[[ -o ?option ]] is true if "option" is a supported option.
05-04-05  A bug in handling file completion with spaces in the names
          has been fixed.
05-03-25 +The SIGWINCH signal is caught by default to keeps the LINES and
      COLUMNS variables in sync with the actual window size.
05-03-25 +Building ksh with SHOPT_REMOTE=1 causes ksh to set --rc if stdin is
      a socket (presumably part of a remote shell invocation.)
05-03-25 +Building ksh with SHOPT_SYSRC=1 causes interactive ksh to source
      /etc/ksh.kshrc (if it exists) before sourcing the $ENV file.
05-03-25 +{first..last[..incr][%fmt]} sequences added to brace expansions
      when braceexpand is enabled.
05-03-03  A bug where a SIGCHLD interrupt could cause a fifo open to fail has
      been fixed.
05-02-25  A bug in which a builtin command run in the background could
      keep a file descriptor open which could cause a foreground
      process to hang has been fixed.
05-02-24  A bug where builtin library commands (e.g., date and TZ) failed to
      detect environment variable changes has been fixed.
05-02-22 +The read builtin and word splitting are now consistent with respect
      to IFS -- both treat IFS as field delimiters.
05-02-22 +The read builtin no longer strips off trailing delimiters that
      are not space characters when there are fewer variables than fields.
05-02-17  A builtin bug on systems where dlsym(libcmd) returns link-time
      bindings has been fixed.
05-02-12  A bug in which the lib_init() function for .paths BUILTIN_LIB
      libraries was not called has been fixed.
05-02-06  A bug on some systems in which moving the write end of a co-process
      to a numbered file descriptor could cause it to close has been fixed.

05-01-11  A bug in the integral divide by zero check has been fixed.
05-01-11 +The -l option has been added to read /etc/profile and
      $HOME/.profile, if they exist, before the first command.
05-01-11  An argument parsing bug that caused `kill -s x -- n' to fail has
      been fixed.
05-01-11 +The .paths file, introduced in ksh93m, which can appear in
      any directory in PATH, now allows a line of the form 'BUILTIN_LIB=.'
      When a command is searched for this directory, and the full path
      matches the path of the built-in version of the command (listed
      by the 'builtin' command) then the built-in version of the command
      is used.  When ksh is built with SHOPT_CMDLIB_DIR=1 then all libcmd
      functions become builtins with the '/opt/ast/bin/' directory prefix.
05-01-10  A bug in which a nameref to a compound name caused a core dump has
      been fixed.
05-01-09  A bug in which some SIGCHLD interrupts (from child processes exiting)
      caused a fatal print/echo error diagnostic has been fixed.
04-12-24  A bug in which some SIGCHLD interrupts (from child processes exiting)
          corrupted the internal process/job list, sometimes causing the shell
      to hang, has been fixed.
04-12-01  A bug in which typeset -Fn truncated less than n digits for large
      numbers has been fixed.
04-11-25  A bug in which standard error could be closed after a redirection
      to /dev/stderr has been fixed.
04-11-17  A bug in which an expansion of the form ${array[@]:3} could expand
          to ${array[0]} when ${array[3]} was not set has been fixed.
04-10-22 +The -E or -orc command line option reads ${ENV-$HOME/.kshrc} file.
04-10-22 +`-o foo' equivalent to `+o nofoo', `-o nobar' equivalent to `+o bar'.
          `--foo' equivalent to `-o foo', `--nofoo' equivalent to `+o foo'
04-10-05 +The .paths file, introduced in ksh93m, which can appear in
      any directory in PATH, now allows a line of the form
      'BUILTIN_LIB=libname'.  When a command is searched for this directory,
      the shared library named by libname will first be searched for a
      built-in version of the command.
04-09-03  <<< here documents now handle quotes in the word token correctly.
04-08-08 +The maximum size for read -n and and read -N was increased from
      4095 to 32M.
04-08-04 +printf %q was modified so that if an no operand was supplied, no
      no output would be generated rather than a quoted empty string.
04-08-01 +The -n and -N options of the read builtin has been modified
      when reading variables with the binary attribute so that the
      data is stored directly rather than through assignment.
04-08-01 +The shcomp command has been modified to process alias commands
      under some conditions.
04-07-31 +The .sh.match variable added in ksh93l, now works like other
      indexed arrays.
04-07-08  A loop optimizer bug which occurs when typeset is used in
      a for or while loop inside a function has been fixed.
04-06-24 +The number of subexpressions in a pattern was increased to 64
      from the current number of 20.
04-06-17 +The -t option to read was modified to allow seconds to be
      specified as any arithmetic expression rather than just
      an integral number of seconds, for example even -t 'sin(.5)'
      is now valid.
04-06-16  Two small memory leak problems were fixed.
04-06-15  A bug in ${var/pattern/"string"} which occurred when string
      contained pattern matching characters has been fixed.
04-05-08  printf $'%d\n' produced an erroneous error message and has
      been fixed.
04-05-24  A bug in which an associative array without any elements could
      cause a core dump when a script with an associative array with
      the same name was declared in a script invoked by name has
      been fixed.
04-05-11  A bug in which an exec statement could close the script that
      is being processed in a script that is run by name causing
      a failure has been fixed.
04-04-28 +If the first character of assignment to an integer variable was 0,
          the variable had been treated as unsigned.  This behavior was
          undocumented and has been removed.
04-04-05  A bug in which the positioning of standard input could be incorrect
      after reading from standard input from a subshell has been fixed.
04-03-30  A bug in the for loop optimizer which in rare cases could cause
      memory corruption has been fixed.
04-03-29 +The preset alias source='command .' has been added.
04-03-29  A bug introduced in ksh93p on some systems in which invoked by
      name with #! on the first line would not get the signals handling
      initialized correctly has been fixed.
04-03-29  A bug introduced in ksh93p in which a HUP signal received by
      a shell that is a session group leader was not passed down to
      its children has been fixed.

04-02-28  --- Release ksh93p  ---
04-02-28 +The ability to apply an append discipline to any variable has
      been added.
04-02-14  A bug in which the exportall option (set -a) would cause incorrect
      results for arrays has been fixed.
04-02-02  A bug in which an exported array would pass more than
      the first element to a script invoked by name has been fixed.
04-02-02  A bug on some systems in which name=value pairs preceding a script
      invoked by name was not getting passed to the script has been fixed.
04-01-20  A bug in which an unset discipline function could cause a core
      dump on some systems has been fixed.
04-01-12  A bug in which a continue or break called outside a loop from
      inside a function defined with name() syntax could affect
      the invoking function has been fixed.
04-01-08  If a command name begins with ~, only filename completion will be
      attempted rather than pathname completion using the builtin editors.
04-01-08  A bug in the vi edit mode in which the wrong repeat count on
      multiple word replacements with the . directive has been fixed.
04-01-06  Backspace characters are now handled correctly in prompt strings.
04-01-06 +The getopts builtin has been modified to accept numerical
      arguments of size long long on systems that support this.
04-01-06  A bug in which unsetting all elements of an associative array
      would cause it to be treated as an indexed array has been fixed.
03-12-15  A bug in which a quoted string ending with an unescaped $ would
      delete the ending $ in certain cases has been fixed.
03-12-05  A bug in which the shell could hang when set -x tracing a command
      when an invalid multibyte character is encountered has been fixed.
03-12-05  On some systems, if the KEYBD trap is set, then commands that use
      the meta key were not processed until return was hit.  This
      has been fixed.
03-12-05  A problem which occurred when the login shell was not a group
      leader that could cause it to fail has been fixed.
03-12-05  A problem in which a shell could core dump after receiving a signal
      that should cause it to terminate while it was in the process
      of acquiring more space has been fixed.
03-12-05 +If ENV is not specified, the shell will default to $HOME/.kshrc
      for interactive shells.
03-11-21  A bug introduced in ksh93o in which the DEBUG trap could get
      disabled after it triggered has been fixed.
03-11-04  A bug in which using arithmetic prefix operators ++ or -- on a
      non-lvalue could cause a core dump has been fixed.
03-11-04  A bug in which leading zeros were stripped from variable
      expansions within arithmetic computation to avoid being treated
      as octal constants when they should not have, has been fixed.
03-10-08  A bug introduced in ksh93o in which a large here document inside
      a function definition could get corrupted has been fixed.
03-09-22  A bug in which the .get discipline function was not being
      called when a string variable was implicitly referenced from
      within a numerical expression has been fixed.
03-09-22  A bug in which a script without a leading #! could get executed
      by /bin/sh rather than the current shell on some systems has
      been fixed.
03-09-12 +To improve conformance with ksh88, leading zeros will be ignored
      when getting the numerical value of a string variable so that
      they will not be treated as octal constants.
03-09-03 +The builtin kill command now processes obsolete invocations
      such as kill -1 -pid.
03-09-02  The restriction on modifying FPATH in a restricted shell (sh -r)
      has been documented.
03-09-02 +The restricted shell (sh -r) has been modified to disallow
      executing command -p.
03-08-07  A bug in which the KEYBD trap was not being invoked when
      characters with the 8th bit set has been fixed.
03-08-02  A parser bug introduced in ksh93o which caused the character
      after () in a Posix function definition to be skipped
      when reading from standard input has been fixed.
03-08-01  A bug in which "${foo#pattern}(x)" treated (x) as if it were
      part of the pattern has been fixed.
03-08-01 +The command -x option has been modified so that any trailing
      arguments that do expand to a single word will be included
      on each invocation, so that commands like command -x mv * dir
      work as expected.

03-07-20  --- Release ksh93o+  ---
03-07-20  A bug in which could cause memory corruption when a posix
      function invoked another one has been fixed.
03-07-15  A bug in which a file descriptor>2 could be closed before
      executing a script has been fixed.
03-07-15  A parsing error for <() and >() process substitutions inside
      command substitution has been fixed.
03-07-15  A parsing error for patterns of the form {...}(...) when
      used inside ${...} has been fixed.
03-07-15  An error in which expanding an indexed array inside a compound
      variable could cause a core dump has been fixed.
03-07-15  A bug in which on rare occasions a job completion interrupt
      could cause to core dump has been fixed.
03-06-26  A bug in which process substitution embedded within command
      substitution would generate a syntax error has been fixed.
03-96-23  A bug in which ${@:offset:len} could core dump when there
      were no arguments has been fixed.
03-96-23  A bug in which ${X[@]:offset:len} could core dump when X
      was unset has been fixed.
03-06-22 +The -x option was added to the command builtin.  If this
      option is on, and the number of arguments would exceed ARG_MAX,
      the command will be invoked multiple times with a subset of
      the arguments.  For example, with alias grep='command -x grep,
      any number of arguments can be specified.
03-06-14  A bug in which could cause a core dump on some systems with
      vi and emacs editors with the MULTIBYTE option has been fixed.
03-06-06  A bug in which the shell could core dump when a script was
      run from its directory, and the script name a symlink to a file
      beginning with .., has been fixed.
03-06-05  A bug in which the shell could core dump when a child process
      that it is unaware of terminates while it is calling malloc()
      has been fixed.
03-06-02 +An option named globstar (set -G) has been added.  When enabled,
      during pathname expansion, any component that consists only of ** is
      matches all files and any number of directory levels.
03-05-30  A bug in which the PATH search could give incorrect results when
      run from directory foo and PATH contained .:foo:xxx has been fixed.
03-05-29 +Some changes were made to the code that displays the prompt in edit
      mode to better handle escape sequences in the prompt.
03-05-27  I added = to the list of characters that mark the beginning of
      a word for edit completion so that filenames in assignments
      can be completed.
03-05-20  A bug in which read -N could hang on some systems when reading
      from a terminal or a pipe has been fixed.
03-05-19  A bug in which the output of uname from a command substitution
      would go to the standard output of the invoking command when
      uname was invoked with a non-standard option has been fixed.
03-05-19  A job control bug which would cause the shell to exit because
      it hadn't take back the terminal has been fixed.  The bug
      could occur when running a function that contained a pipeline
      whose last element was a function.
03-05-19  A job control timing bug introduced in ksh93o on some systems
      which could cause a pipeline to hang if the first component
      completed quickly has been fixed.
03-05-13 +The read builtin has been modified so that the builtin editors
      will not overwrite output from a previous incomplete line.
03-05-13  A bug in which the name of an identifier could have the string
      .sh. prefixed to it after expanding a variable whose name begins
      with .sh. has been fixed.
03-05-13  A bug in the expansion of $var for compound variables in which
      some elements would not be output when the name was a prefix
      of another name in the compound variable has been fixed.
03-05-08  The last item in the ksh93o release on 03-01-02 has been
      altered slightly to preserve the leading 0's when the
      preceding character is a digit.  Thus, with typeset -LZ3 x=10,
      $(( 1$x)) will be 1010 whereas $(( $x) will be 10.
03-04-25  A bug in which if x is a name reference, then nameref y=x.foo
      did not follow x has been fixed.

03-03-18  --- Release ksh93o  ---
03-03-18 +A -N unary operator was added to test and [[...]] which returns
      true if the file exists and the file has been modified since it
      was last read.
03-03-18 +The TIMEFORMAT variable was added to control the format for
      the time compound command.  The formatting description is
      described in the man page.
03-03-06 +A -N n option was added to read which causes exactly n bytes
      to be read unlike -n n which causes at most n bytes to be read.
03-03-03 +Three new shell variables were added.  The variable .sh.file
      stores the full pathname of the file that the current command
      was found in.  The variable .sh.fun names the current function
      that is running.  The variable .sh.subshell contains the depth
      of the current subshell or command substitution.
03-03-03 +When the DEBUG trap is executed, the current command line after
      expansions is placed in the variable .sh.command.  The trap
      is also now triggered before each iteration of a for, select,
      and case command and before each assignment and redirection.
03-02-28 +Function definitions are no longer stored in the history file so
      that set -o nolog no longer has any meaning.
03-02-28 +All function definitions can be displayed with typeset -f not
      just those stored in the history file.  In addition, typeset +f
      displays the function name followed by a comment containing the
      line number and the path name for the file that defined this function.
03-02-28  A bug in which the value of $LINENO was not correct when executing
      command contained inside mult-line command substitutions has been
      fixed.
03-02-19 +Since some existing ksh88 scripts use the undocumented and
      unintended ability to insert a : in front of the % and # parameter
      expansion operators, ksh93 was modified to accept :% as equivalent
      to % and :# as equivalent to # with ${name op word}.
03-02-14  A bug which could cause a core dump when reading from standard
      error when standard error was a pty has been fixed.
03-02-14 +The shell arithmetic was modified to use long double on systems
      that provide this data type.
03-02-09  A bug in which a function located in the first directory in FPATH
      would not be found when the last component of PATH was . and the
      current directory was one of the directories in PATH has been fixed.
03-02-07 +The trap and kill builtin commands now accept a leading SIG prefix
      on the signal names as documented.
03-02-05  A bug in the expansion of ${var/$pattern}, when pattern contained
      \[ has been fixed.
03-02-05  A bug in which .sh.match[n], n>0, was not being set for substring
      matches with % and %% has been fixed.
03-01-15  A bug in which getopts did not work for numerical arguments specified
      as n#var in the getopts string has been fixed.
03-01-09  A bug in which using ${.sh.match} multiple times could lead to
      a memory exception has been fixed.
03-01-06  A bug in the expansion of ${var/pattern/$string} in the case that
      $string contains \digit has been fixed.
03-01-02 +A -P option was added for systems such as Solaris 8 that support
      profile shell.
03-01-02  For backward compatibility with ksh88, arithmetic expansion
      with ((...)) and let has been modified so that if x is a zero-filled
      variable, $x will not be treated as an octal constant.

02-12-05  --- Release ksh93n+  ---
02-11-30  A bug that can show up in evaluating arithmetic statements that
      are in an autoloaded function when the function is autoload from
      another function has been fixed.
02-11-30  An optimization bug in which an expansion of the form ${!name.@},
      which occurred inside a for or a while loop, when name is a name
      reference, has been fixed.
02-11-18  A bug in which modifying array variables in a subshell could leave
      side effects in the parent shell environment has been fixed.
02-11-18  A memory leak when unsetting an associative array has been fixed.
02-11-14 +The code to display compound objects was rewritten to make
      it easier for runtime extensions to reuse this code.
02-11-14 +A change was made to allow runtime builtins to be notified when
      a signal is received so that cleanup can be performed.
02-10-31 +User applications can now trap the ALRM signal.  Previously,
      the ALRM signal was used internally and could not be used
      by applications.
02-10-31  A bug in which signals received while reading from a coprocess
      for which traps were set was not handled correctly has been fixed.
02-10-31  A bug in which a file opened with exec inside a subshell could
      be closed before the subshell completed has been fixed.
02-10-21  A bug in which setting PATH or FPATH inside a function might not
      take effect has been fixed.
02-10-21  A bug which could cause a core dump when a local SECONDS variable
      is defined in a function has been fixed.
02-10-15  A bug in which the associate array name operator ${!array[@]}
      could return the same name multiple times has been fixed.
02-10-15  A bug in which the zero'th element of an associative array was
      not getting set when an assignment was made without a subscript
      specified has been fixed.

02-09-30  --- Release ksh93n  ---
02-09-30 +The maximum indexed array size was increased to 16Megs.
02-09-30  A bug which could cause a core dump when changing attributes
      of associative array has been fixed.
02-09-30  A bug in which exporting an array variable would not export the
      0-th element has been fixed.
02-09-30  A bug in which an array assignment of the form a=($a ...) would unset
      'a' before the right hand side was evaluated has been fixed.
02-09-27  A bug in which the error message for ${var?message} when var was
      null or unset did not contain the variable name var has been fixed.
02-09-27  A bug in which closing file descriptors 0 through 2 could
      cause a subsequent here document to fail has been fixed.
02-09-14  A bug in whence which occurs when the specified name contained
      a / has been fixed.
02-09-14  A bug in the parser for strings of the form name$((expr))=value
      has been fixed.
02-09-14  A for loop optimization bug in which the number of elements in
      an array was treated as an invariant has been fixed.
02-09-09  A bug in which redirection or closing of a file descriptor between
      3 and 9 could cause a subsequent here document to fail has been
      fixed.
02-09-09  A bug in which a background job was not removed from the job list
      when a subshell completed has been fixed, for example (prog&).
02-09-03  A bug in which an assignment of the form name=(integer x=3)
      could be interpreted as an array assignment rather than a
      compound variable assignment has been fixed.
02-08-19  A command completion bug which occurred on file systems that
      are case insensitive has been fixed.
02-08-19  A bug which could lead to an exception on some systems (for
      example FREEBSD) which occurred when setting PATH has been fixed.
02-08-11  A bug in arithmetic rounding in which a value input as a decimal
      string would output as a rounded version of the string has
      been fixed.
02-08-11  A bug in which the last character could be deleted from shell
      traces and from whence when called from a multibyte locale
      has been fixed.
02-08-01  A bug which could cause a core dump to occur when a shell script
      is executed while a coprocess is running that has closed the
      output pipe has been fixed.
02-08-01  A bug in which command completion in multibyte mode could
      corrupt memory for long command lines has been fixed.

02-06-17  --- Release ksh93n-  ---
02-06-17  A bug in which user defined macros could cause a core dump in
      with MULTIBYTE mode has been fixed.
02-06-17  A bug in which printf format specifiers of the form %2$s were causing
      a core dump has been fixed.
02-06-17  A bug in which setting stty to noecho mode did not prevent the
      echoing of characters by ksh when emacs or viraw mode
      was enabled has been fixed.
02-06-17  A bug in which background job completion could cause the sleep
      builtin to terminate prematurely has been fixed.
02-06-17  A bug in which the shell could core dump if getopts was called
      when the OPTIND variable contained a negative value has been fixed.
02-06-10 +The edit mode prompt has been modified to handle escape sequences.
02-06-10  A bug which occurred for interactive shells in which the builtin
      cat command was used in command substitution on a file whose
      size was larger than PIPE_BUF has been fixed.
02-06-10  A bug in which the trap on ERR was not being processed when
      set inside a function has been fixed.
02-06-07  A bug in which function definitions could cause the history count
      to be decremented by one (and even become negative) has been fixed.
02-06-05  A bug in read in which share mode could be enabled has been fixed.
02-05-28  A bug which could occur when the last command of a script was
      a case statement and the action selected ended in ;& instead of ;;
      has been fixed.
02-05-23  A bug with unary + introduced in ksh93k has been fixed.
02-05-07  A bug in substitutions of the form ${var/pattern/string} in which
      a backslash was inserted in the replacement string when it contained
      a special pattern character has been fixed.
02-05-01  A bug in the emacs edit mode which occurred in versions compiled
      for multibyte character sets which occurred when a repeated search
      was requested after a long line had been returned for the previous
      search has been fixed.
02-04-02 +vi and emacs edit modes were modified so that tab completion is
      disabled when invoked from the read built-in.

02-03-26  --- Release ksh93m+  ---
02-03-26  A bug in which \ was not handled correctly when used in file
      expansion has been fixed.
02-02-18  A bug in which lines beginning with a # were deleted from here
      documents when the here-document delimiter was followed by
      a comment has been fixed.
02-12-06  An optimization bug in which ${!x[@]) was treated as invariant in
      a for loop has been fixed.
02-02-06  A bug in which the ERR trap is not cleared for a script invoked
      by name from within a function has been fixed.
02-01-08  A bug in which a shell script executed from within a subshell
      could cause this script to have an invalid pointer leading
      to a memory fault has been fixed.
02-01-07 +Added here documents of the form <<< word (as per zsh) which
      is equivalent to << delim\nword\ndelim.
02-01-07  A bug in which the first word of a compound assignment,
      x=(word ...), was treated as a reserved word has been fixed.
02-01-07  A bug in the handling of \ when noglob was enabled and a
      substitution of the form ${word op pattern} occurred in the
      same word has been fixed.
02-01-07 +A compilation option, CMDLIB_BLTIN in the file OPTION, has
      been added.  When this options is set, all commands implemented
      in libcmd become shell builtin commands by default.
02-01-07  A bug in which builtin foo, where foo is already a builtin
      would result in the builtin foo getting removed has been fixed.
02-01-07  A bug which the shell executed a command found in the current
      directory when PATH have no valid directories has been fixed.
01-11-28  The value of $? was not being set when called with exit.
01-11-28  If the last command was of the form (...) and a trap on EXIT or
      ERR was set, and the command inside () modified the trap, then
      the original trap wasn't executed.
01-11-26 +The value for 0 is now preceded by the base number when
      the base was not 10.
01-11-26 +The default has compilation mode has been changes so that
      viraw mode will always be on.

01-10-31  --- Release ksh93m  ---
01-10-31  A for loop optimizer bug for subshells contained withing for
      loops has been fixed.
01-10-16  typeset without arguments no longer outputs variable names
      that do not have any attributes that are set.
01-10-16  A bug introduced in ksh93l in which assignments specified with
      the exec built-in were not being expanded properly has been
      fixed.
01-10-11  An optimization bug in which ${!x) was treated as invariant in
      a for loop has been fixed.
01-10-11  Unsigned integer variables in bases other than 10 are printed now
      expand in that base with the base prefix.
01-10-10  A number of typos in the self generating man pages for shell
      built-ins have been fixed.
01-10-04  The self generated man pages for hist and fc were not working
      correctly and have been fixed.
01-10-03  Yet another optimizer bug in which shell patterns were
      treated as invariants has been fixed.
01-09-27  Two bugs relating to multibyte history searches and to find
      have been fixed.
01-09-27  A bug introduced in ksh93k in which the PATH searching was
      not restored after running a command with an assignment list
      has been fixed.
01-09-26  A bug in which a zero filled field was treated as octal when
      converted to integer has been fixed.
01-09-26  Yet another bug in the optimization of for loops related to
      recursive functions with break or continue statements has been fixed.
01-09-25 +The exponentiation operator ** was added to the shell arithmetic
      evaluation.  It has higher precedence than * and is left
      associative.
01-09-25  The code was modified to use the ast multibyte macros
      and functions for handing multibyte locales.
01-09-25 +The expansion ${parameter:offset:length} now handles negative
      offsets which cause offsets to be measured from the end.
01-09-25  Some spelling errors in the documentation were corrected.
01-09-24 +The /dev/tcp/host/port and /dev/udp/host/port now allow
      the ports to be specified by service name.
01-09-24 +The change staring with ksh93g in which the the appropriate
      library path variable is prepended with a corresponding library
      directory has been modified.  With the new method, only the
      library path defined in the file named .paths in the directory
      where the executable is found will be modified.  See the
      man page for more details.
01-09-23 +The .fpath file (see ksh93h) is no longer looked for in each
      directory on the path to locate function directories.  The
      file named .paths is used instead.
01-09-23  A bug in which IFS was not being restored after being changed in
      a subshell has been fixed.
01-09-16 +With the vi and emacs edit modes, after a list of command
      or functions is generated with = or M-= respectively,
      any element from the list can be pasted on the command line
      by preceding the = or M-= with a numeric parameter specifying
      the position on the list.
01-09-16  A bug in ksh93l caused command completion not to find aliases
      and functions.  Command listing from the edit mode was presented
      in reverse order.  This has been fixed.
01-09-13  Another bug in the optimization of for loops related to subshells
      when traps were set has been fixed.
01-09-07  A change in ksh93l caused brace expansion to stop working
      and this has been fixed.
01-09-04  A bug introduced in ksh93k in which an arithmetic statement
      within a function that used name references did not follow the
      reference has been fixed.
01-09-04  A bug introduced in ksh93l in which export -p did not prefix
      each export with the word export has been fixed.
01-08-29  A bug in multibyte input which occurred when a partial multibyte
      character was received has been fixed.
01-08-29  A bug introduced in ksh93l which could cause a core dump
      when an assignment list containing PATH is specified inside
      command substitution has been fixed.
01-08-09  Another bug in the optimization of for loops in ksh93l caused
      errors in recursive functions using local variables that
      contained for loops has been fixed.
01-07-27  A bug in which IFS would be unset after a command substitution
      inside a here document has been fixed.
01-07-26  To conform to the POSIX standard, if you invoked ksh name,
      and name does not contain a /,  it will first try to run
      one in the current directory whether it is executable or not
      before doing a path search for an executable script.  Earlier
      versions first checked for an executable script using the
      PATH variable.
01-07-23  A bug in which unset -f invoked in a subshell could unset a
      function defined in the parent has been fixed.
01-07-16  A bug in the optimization of for loops in ksh93l caused
      name references to be treated as invariants has been fixed.
01-07-09  A bug in which a discipline function applied to a local variable
      could cause a shell exception has been fixed.  Discipline
      functions can only be specified for global variables.

01-06-18  --- Release ksh93l  ---
01-06-18  A bug in assigning integers larger than can be represented as
      long integers to floating point variables has been fixed.
01-06-18  A bug in the handling of unsigned integers (typeset -ui) has
      been fixed.
01-06-04  The evaluation of the PS1 prompt no longer effects the value
      of the $? variable.
01-06-01  A small memory leak from subshells has been fixed.
01-05-22  A bug in which attributes for variables that did not have
      values would be lost after a subshell has been fixed.
01-05-22 +The %R format has been added to convert a shell pattern into
      an extended regular expression.
01-05-22 +The escape sequences \e, \cX, \C[.collating-element.], and
      \x{hex} have been added to ASCII-C strings and to printf format
      strings.
01-05-20 +Patterns of the form {n}(pattern) and {m,n}(pattern) are now
      recognized.  The first form matches exactly n of pattern whereas,
      the second form matches from m to n instances of pattern.
01-05-20 +The shell allows *-(pattern), +-(pattern),  ?-(pattern),
      {m,n}-(pattern}, and @-(pattern) to cause the minimal
      match of pattern to be selected whenever possible rather
      than the maximal (greedy) match.
01-05-20 +The character class [:word:] has been added to patterns.
      The word class is the union of [:alnum:] and the character _.
01-05-20 +Inside (...) pattern groups, the \ character is now treated
      specially even when in an enclosing character class.  The
      sequences, \w, \d, \s are equivalent to the character classes
      word, digit, and space respectively.  The sequences \W, \D,
      and \S are their complement sets.
01-05-20 +The shell now recognizes pattern groups of the form
      ~(options:pattern) where options or :pattern can be omitted.
      Options use the letters + and - to enable and disable options
      respectively.  The option letters g (greedy), i (ignore case)
      are used to cause maximal matching and to cause case
      insensitive matching respectively.  If :pattern is also
      specified, these options are only in effect while this
      pattern is being processed.  Otherwise, these options remain
      in effect until the end of the pattern group that they are contained
      in or until another ~(...) is encountered.  These pattern groups
      are not counted with respect to group numbering.
01-05-14  When edit completion, expansion, or listing occurs in the
      middle of a quoted string, the leading quote is ignored when
      performing the completion, expansion, or listing.
01-05-14  A small memory leak from subshells has been fixed.
01-05-10  A bug in which open files were not restored after a subshell
      that had used exec to replace a file has been fixed.
01-05-10 +Redirection to a null file name now generates an error message.
01-05-09  The shell now rejects some invalid parameter substitutions that
      were previously processed in undefined ways.
01-05-09  A bug in which the output of select was not flushed before the
      read when input did not come from the terminal has been fixed.
01-05-08  A bug in which job ids would not be freed for interactive shells
      when subshells ran built-ins in the background has been fixed.
01-05-08 +The FPATH variable now requires an explicit . to cause the
      current directory to be treated as a function directory.
01-05-08  A bug in read -n when echo mode was disabled has been fixed.
01-05-07  A bug in which function definitions could be listed as part
      of the history has been fixed.
01-04-30 +This release uses a new and often much faster pattern matcher than
      earlier releases.
01-04-30 +An optimizer now eliminates invariant parameter expansions from
      for while and until loops.
01-04-30 +The variable .sh.match is set after each pattern match (# % or /)
      in a variable substitution.  The variable .sh.match is an
      indexed array with element 0 being the complete match.
      The array is only valid until the next subsequent pattern
      match or until the value of the variable changes which ever
      comes first.
01-04-30 +A self generating man page has been added to shcomp.  Also,
      shcomp now stops compiling when it finds an exit or exec
      command and copies the remainder so that it can be used
      for standard input.
01-04-30 +The shcomp command was modified so that it can work in an
      EBCIDIC environment and that binary scripts are portable
      across environments.
01-04-30  A bug in the handling of a trailing : in PATH has been fixed.
01-04-30  A bug in which the builtin version of a command would get invoked
      even though the full pathname for the command was specified
      has been fixed.
01-04-30  A bug in which read would loose the last character when
      reading the last line of a file that did not contain a new-line
      character has been fixed.
01-04-23  A bug on some systems in which in vi mode the end of file
      character and end of line character could be swapped has
      been fixed.
01-04-23  A bug on some systems in which invoking a shell script that
      did not have execute permission could set the exit value to
      127 rather than 126 has been fixed.
01-04-20  A bug in which read -n from a pipe would block if fewer than
      n characters was received has been fixed.
01-04-09  A bug in which invalid patterns, for example, ) by itself,
      was not treated as a string has been fixed so that if i=')',
      then [[ $i == $i ]] is true.
01-04-09 +The shell arithmetic now interprets C character constants.
01-04-09  A bug in which a non-zero return from a function defined
      with the function reserved word did not trigger the ERR
      trap or exit with set -e has been fixed.
01-04-02  A bug on some systems, in which characters above 127 were
      not displayed correctly in vi or emacs edit mode has been fixed.
01-04-02  A bug on some systems, introduced in the 'k' point release, in
      which the erase character in viraw mode was moving the cursor
      to the left without erasing the character has been fixed.
01-04-02  On some systems the wcwith() function was returning a wrong
      value for characters and caused characters to be displayed
      incorrectly from the shell edit modes.  A work around for
      this problem has been added.
01-03-26  A bug in which valid scripts could produce syntax errors
      when run with locales that considered characters such as "'"
      to be space characters has been fixed.
01-03-20  A bug in which an syntax error in an arithmetic expression
      entered interactively could cause the shell to go into
      an infinite loop outputting the error message has been fixed.
01-03-10 +ksh93 accepts -l as a synonym for -L in test on systems for
      which /bin/test -l tests for symbolic links.
01-03-10  A bug in parsing scripts in which { and } are used in place of
      in and esac in case statements embedded in compound commands
      has been fixed.  Use of { and } for in and esac is obsolete.
01-03-06  A bug in which an argument of the form foo=bar was not
      being passed correctly to a traced function whose name
      was foo has been fixed.
01-03-02  Using $(trap -p name) did not print the name of the current
      trap setting for trap name.
01-02-26  Exported floating point variables gave incorrect results
      when passing them to ksh88.  This has been fixed.
01-02-25  A race condition in which a coprocess which completed too quickly
      would not allow subsequent coprocesses to start has been fixed.
01-02-25  The 'g' format specifier is now handled by printf.  It had
      inadvertently been omitted.
01-02-20  The + was not being displayed during an execution trace
      with the += assignment operator.
01-02-19  The error message which occurs when the interpreter name
      defined on the #! line does not exist is more informative.
01-02-19  A bug in which $0 would not be set correctly when a
      script with #! was invoked by full pathname from the
      directory of the script has been fixed.
01-02-19  A shell script did not always pick up tty mode changes
      made by external commands such as stty which could
      effect the behavior of read.
01-02-19  The -u, -g, and -k unary tests did not give the correct
      results when used with negation and this has been fixed.

01-02-05  --- Release ksh93k+  ---
01-02-05  The sequence \<newline> inside $'...' was not incrementing
      the line count and this has been fixed.
01-02-05 +Modified expansion of "${@-}" so that if no arguments are set
      it results in null string rather than nothing.
01-02-02  memory leak problem with local variables in functions fixed.
01-01-25 +allow arithmetic expressions with float%int and treat them
      as ((int)float)%int rather than as an error.
01-01-19  read -n1 was not working and has been fixed.
01-01-17 +ksh now handles the case in which a here document in command
      substitution $() is terminated by the trailing ).  Previously,
      a new-line was needed at the end of the delimiter word.
01-01-02  A bug in which a KEYBD trap would cause a multi-line token
      to be processed incorrectly has been fixed.
00-12-10 +Arithmetic integer constants can now have L and U suffices.
00-12-10  A bug in the processing of arithmetic expressions with compound
      variables when the -n option is on has been fixed.
00-12-08  A bug in M-f and M-b from emacs mode has been fixed.  This
      bug only occurs when ksh93 is compiled without MULTIBYTE enabled.
00-11-29  A bug in which jobs -p would yield 0 for background
      jobs run in a script has been fixed.
00-11-21  A bug in integer arrays in which the number of elements is
      incorrect when the ++ operator is applied to a non-existing
      element has been fixed.  For example, integer x; ((x[3]++)).
00-11-20  A timing bug in which the shell could reset the terminal
      group to the wrong value in the case that the a new process
      changes the terminal group during startup has been fixed.

00-10-27  --- Release ksh93k  ---
00-10-27  Using tab for completion now works only when applied
      after a non-blank character at the end of the current line.
      In other case a tab is inserted.
00-10-27  A bug in the emacs edit mode for ^X^E has been fixed.
      The ^X^E sequence is supposed to invoke the full editor
      on the current command.
00-10-18  A bug in which expansions of the form ${var//pattern/string}
      did not work correctly when pattern was '/' or "/" has
      been fixed.
00-10-18 +The output format for indexed arrays in compound variables
      has been modified so that it can be used as input.
00-10-18  Assignments with name references (typeset -n) will now
      implicitly unreference an existing name reference.
00-10-17  A bug the += append operator when a single array element
      is appended to a variable that is not an array has been fixed.
00-10-16  A bug in which the SIGCONT signal was being sent to
      each process will kill -0 or kill -n 0 has been fixed.
00-10-12 +The arithmetic evaluation portion has been rewritten to
      perform a number of optimizations.
00-10-10  A bug in which name prefix matching ${!name.*} was not
      checking name to see if it was a name reference has been fixed.
00-09-26  A bug in the multibyte version in which the width of for
      non-printing characters was not correct has been fixed.

      has been fixed.
00-08-08  Removed build dependency on iswprint() and iswalph().
00-07-20  In some cases the read builtin would read more than a single
      line from a pipe on standard input and therefore leave the seek
      position in the wrong location.
00-07-05 +If the directory / is on the path, a / will not be inserted
      between the directory and the file name during path searching
      to avoid searching // for systems that treat this specially.
00-06-26  A bug in which on rare occasions wait could return before all
      jobs have completed has been fixed.
00-06-21  A bug in which backspace did not work correctly during the
      R replace directive in vi-mode has been fixed.
00-06-12 +Added variable name completion/expansion/listing  to the set of
      completions.  Variable name completions begin with $ or "$ followed
      by a letter.
00-05-09  --- Release ksh93j  ---

INIT.READMEThe INIT package is required by all but the standalone and self
extracting archive packages. It contains the package command, support
scripts, and utilities.  The package command installs binary packages,
makes source packages, and generates new package tarballs.

Source Package Installation Instructions:

  (1) Do not install packages as root/super-user. Although some components may
      have setuid executables, few must be owned by root. These are best
      changed manually when the security implications are understood.
  (2) Choose a package root directory and cd to it. This will be a local work
      area for all packages.
  (3) These instructions bypass the click to download package links on the
      download site. If you already clicked, or if your system does not have
      curl(1), hurl(1), lynx(1) or wget(1) then use the alternate instructions
      for (3),(4),(5) in plan B below. Plan B installs the hurl(1)
      script which works with ksh and modern bash. The top level URL is:
        URL=http://www.research.att.com/sw/download
  (4) If the bin/package script does not exist then run:
        test -d bin || mkdir bin
        url=$URL/package
        (wget -O - $url||curl -L $url||hurl $url) > bin/package
        chmod +x bin/package
  (5) Determine the list of package names you want from the download site, then
      use the package(1) command to do the actual download:
        bin/package authorize "NAME" password "PASSWORD" \
            setup source $URL PACKAGE ...
      (Refer to the AUTHORIZATION paragraph on the main download page for
      NAME/PASSWORD details.)  This downloads the closure of the latest
      source package(s); covered and up-to-date packages are not downloaded again unless
      package force ... is specified. Package content is verified using md5sum.
      If the package root will contain only one architecture then you can install in bin and
      lib instead of arch/HOSTTYPE/bin and arch/HOSTTYPE/lib by running this
      instead:
        bin/package authorize "NAME" password "PASSWORD" \
            flat setup source $URL PACKAGE ...
      To update the same packages from the same URL run:
        bin/package setup source
  (6) Build and install; all generated files are placed under arch/HOSTTYPE
      ($INSTALLROOT), where HOSTTYPE is the output of bin/package (with no
      arguments.) name=value arguments are supported; CC and debug=1 (compile
      with -g instead of -O) are likely candidates. The output is written to
      the terminal and captured in $INSTALLROOT/lib/package/gen/make.out:
        bin/package make
  (7) List make results and interesting errors:
        bin/package results
      Run the regression tests:
        bin/package test
      List test results and errors:
        bin/package results test
  (8) The generated binaries are position independent, i.e., they do not
      contain hard-coded paths. However, commands with related files, like
      file(1) and nmake(1), require the path of the bin directory to be
      exported in PATH.
  (9) You can run the binaries directly from the package root, or you can
      install them in a public root after you are satisfied with the make and
      test actions (requires the AT&T nmake(1) command):
        bin/package flat install DIRECTORY PACKAGE
      This will install in DIRECTORY/bin and DIRECTORY/lib. If you want to
      preserve the arch/HOSTTYPE hierarchy under DIRECTORY then omit the
      flat argument. If you don't have nmake(1) then the following will do a
      flat install:
        cd $INSTALLROOT
        cp -p -r bin lib include DIRECTORY
  (10) To summarize, after the first time the download, build, and test cycle
      for the latest source release is:
        bin/package setup source
        bin/package make
        bin/package test

Source Package Installation Instructions -- Plan B:

  (3) Create the subdirectory lib/package/tgz and download all package archives
      into that directory.
  (4) If the bin/package script does not exist then manually read the INIT
      source package:
        gunzip < lib/package/tgz/INIT.YYYY-MM-DD.tgz | tar xvf -
      Note that some browsers automatically unzip downloaded without warning.
      If the gunzip fails try:
        tar xvf - lib/package/tgz/INIT.YYYY-MM-DD.tgz
      If your system does not have tar(1) or gunzip(1) then download the ratz
      source package, compile it, and manually read the INIT
      source package:
        mkdir bin
        cp lib/package/tgz/ratz.YYYY-MM-DD.c lib/package/tgz/ratz.c
        cc -o bin/ratz lib/package/tgz/ratz.c
        bin/ratz -lm < lib/package/tgz/INIT.YYYY-MM-DD.tgz
  (5) Read all unread package archive(s):
        bin/package read
      Both source and binary packages will be read by this step.

All recorded changes follow.
