+  summary: Regular expression pattern matching using Perl 5 syntax and semantics.
+  description: |
+    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.
