Fedora Update Notification

2015-08-07 10:01:27
--------------------------------------------------------------------------------

Name        : pcre
Product     : Fedora 22
Version     : 8.37
Release     : 3.fc22
URL         : https://www.pcre.org/
Summary     : Perl-compatible regular expression library
Description :
Perl-compatible regular expression library.
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. The header file
for the POSIX-style functions is called pcreposix.h.
