/*
 * Usage: regex [-v string] [-e] pattern [template] [pattern [template] ...]
 *
 * The first form takes a string and matches it against patterns until
 * there is a match.  Patterns are regular expression as described in
 * regcmp(3X).  When a match is found, the corresponding template is
 * returned in the output stream.  Templates may be arbitrary strings,
 * but if the string $m0, $m1, ..., $m9 appear in the string, then they
 * will be expanded to the corresponding pattern that matched within
 * (...)$0 through (...)$9 parts of the pattern.
 * For example:
 *		regex "0123456789" '.{2}(.{3})$0' 'hi $m0'
 * would return the string: 'hi 234'.
 * The default template is '$m0$m1$m2$m3$m4$m5$m6$m7$m8$m9'.
 *
 * The -v option causes string to be parsed instead of stdin
 *
 * The -e option causes the resulting template to be evaluated
