"[+NAME?msgcpp - C language message catalog preprocessor]"
"[+DESCRIPTION?\bmsgcpp\b is a C language message catalog preprocessor."
" It accepts \bcpp\b(1) style options and arguments. \bmsgcpp\b"
" preprocesses an input C source file and emits keyed lines to the"
" output, usually for further processing by \bmsgcc\b(1). \bmsgcc\b"
" output is in the \bgencat\b(1) syntax. Candidate message text is"
" determined by arguments to the \bast\b \b<error.h>\b and"
" \b<option.h>\b functions. The \bmsgcpp\b keyed output lines are:]{"
" [+cmd \acommand\a?\acommand\a is a candidate for \b--??keys\b"
" option string generation. Triggered by"
" \bb_\b\acommand\a\b(int argc,\b in the input.]"
" [+def \aname\a \astring\a?\aname\a is a candidate variable with"
" string value \astring\a.]"
" [+str \astring\a?\astring\a should be entered into the catalog.]"
" [+var \aname\a?If \bdef\b \aname\a occurs then its \astring\a value"
" should be entered into the catalog.]"
" }"
"[+?The input source file is preprocessed with the \bpp:allpossible\b"
" option on. This enables non-C semantics; all source should first"
" be compiled error-free with a real compiler before running \bmsgcpp\b."
" The following changes are enabled for the top level files (i.e.,"
" included file behavior is not affected):]{"
" [+(1)?All \b#if\b, \b#ifdef\b and \b#ifndef\b branches"
" are enabled.]"
" [+(2)?The first definition for a macro is retained, even when"
" subsequent \b#define\b statements would normally"
" redefine the macro. \b#undef\b must be used to"
" redefine a macro.]"
" [+(3)?Macro calls with an improper number of arguments are"
" silently ignored.]"
" [+(4)?\b#include\b on non-existent headers are silently"
" ignored.]"
" [+(5)?Invalid C source characters are silently ignored.]"
" }"
"[+?\b\"msgcat.h\"\b is included if it exists. This file may contain macro"
" definitions for functions that translate string arguments. If \afoo\a"
" is a function that translates its string arguments then include the"
" line \b#define \b\afoo\a\b _TRANSLATE_\b in \bmsgcat.h\b or specify"
" the option \b-D\b\afoo\a\b=_TRANSLATE_\b. If \abar\a is a function"
" that translates string arguments if the first argument is \bstderr\b"
" then use either \b#define \b\abar\a\b _STDIO_\b or"
" \b-D\b\abar\a\b=_STDIO_\b.]"
"[+?The macro \b_BLD_msgcat\b is defined to be \b1\b. As an alternative to"
" \bmsgcat.h\b, \b_TRANSLATE_\b definitions could be placed inside"
" \b#ifdef _BLD_msgcat\b ... \b#endif\b.]"

"\n[ input [ output ] ]\n"
