Description: New Perl Compatible Regular Expression Library- 8 bit
runtime files
This is PCRE2, the new implementation of PCRE, a library of functions
to support regular expressions whose syntax and semantics are as
close as possible to those of the Perl 5 language. New projects
should use this library in preference to the older library,
confusingly called pcre3 in Debian.
.
This package contains the 8 bit runtime library.
