------------------------------------------------------------------------------
-- This package implements roughly the same set of regular expressions as
-- are available in the Perl or Python programming languages.
-- This is an extension of the original V7 style regular expression library
-- written in C by Henry Spencer. Apart from the translation to Ada, the
-- interface has been considerably changed to use the Ada String type
-- instead of C-style nul-terminated strings.
-- See file s-regpat.ads for full documentation of the interface
------------------------------------------------------------
-- Summary of Pattern Matching Packages in GNAT Hierarchy --
------------------------------------------------------------
-- There are three related packages that perform pattern maching 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/s-regpat.adb)
-- This is a more complete implementation of Unix-style regular
-- expressions, copied from the Perl regular expression engine,
-- written originally in C by Henry Spencer. It is functionally the
-- same as that library.
-- 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.
