-      The PCRE library is a set of functions that implement regular
-      expression pattern matching using the same syntax and semantics as
-      Perl 5. PCRE has its own native API, as well as a set of wrapper
-      functions that correspond to the POSIX regular expression API. The
-      PCRE library is free, even for building proprietary software.
