%description
PCRE has its own native API, but a set of "wrapper" functions that are based on
the POSIX API are also supplied in the library libpcreposix. Note that this
just provides a POSIX calling interface to PCRE: the regular expressions
themselves still follow Perl syntax and semantics.

This package contains a grep variant based on the PCRE library.

Install this package if you want do compile applications using the PCRE
library.

The header file for the POSIX-style functions is called pcreposix.h. The
official POSIX name is regex.h, but I didn't want to risk possible problems
with existing files of that name by distributing it that way. To use it with an
existing program that uses the POSIX API, it will have to be renamed or pointed
at by a link.
