Regular Expressions
===================

A "regular expression" (or "regexp") is a pattern that describes a
whole class of strings.  A full description of regular expressions and
their syntax is beyond the scope of this manual; an introduction can be
found in the Emacs manual (*note Syntax of Regular Expressions:
(emacs)Regexps., or in many general Unix reference books.

If your system does not include a POSIX regular expression library, and
you have not linked Guile with a third-party regexp library such as Rx,
these functions will not be available.  You can tell whether your Guile
installation includes regular expression support by checking whether the
`*features*' list includes the `regex' symbol.

Regexp Functions

Functions that create and match regexps.

Match Structures

Finding what was matched by a regexp.

Backslash Escapes

Removing the special meaning of regexp metacharacters.

Rx Interface

Tom Lord's Rx library does things differently.

[FIXME: it may be useful to include an Examples section.  Parts of this
interface are bewildering on first glance.]
