--- Simple Regular expression matching
-
--- This package provides a simple implementation of a regular expression
--- pattern matching algorithm, using a subset of the syntax of regular
--- expressions copied from familiar Unix style utilities.

--- See file s-regexp.ads for full documentation of the interface

--- Summary of Pattern Matching Packages in GNAT Hierarchy --
-------------------------------------------------------------
-
--- There are three related packages that perform pattern matching functions.
--- the following is an outline of these packages, to help you determine
--- which is best for your needs.
-
--- GNAT.Regexp (files g-regexp.ads/s-regexp.ads/s-regexp.adb)
--- This is a simple package providing Unix-style regular expression
--- matching with the restriction that it matches entire strings. It
--- is particularly useful for file name matching, and in particular
--- it provides "globbing patterns" that are useful in implementing
--- unix or DOS style wild card matching for file names.
-
--- GNAT.Regpat (files g-regpat.ads/s-regpat.ads/g-regpat.adb)
--- This is a more complete implementation of Unix-style regular
--- expressions, copied from the original V7 style regular expression
--- library written in C by Henry Spencer. It is functionally the
--- same as this library, and uses the same internal data structures
--- stored in a binary compatible manner.
-
--- GNAT.Spitbol.Patterns (files g-spipat.ads/g-spipat.adb)
--- This is a completely general pattern matching package based on the
--- pattern language of SNOBOL4, as implemented in SPITBOL. The pattern
--- language is modeled on context free grammars, with context sensitive
--- extensions that provide full (type 0) computational capabilities.
