+dnl @synopsis AX_PATH_LIB_PCRE [(A/NA)]
+dnl
+dnl check for pcre lib and set PCRE_LIBS and PCRE_CPPFLAGS accordingly.
+dnl
+dnl also provide --with-pcre option that may point to the $prefix of
+dnl the pcre installation - the macro will check $pcre/include and
+dnl $pcre/lib to contain the necessary files.
+dnl
+dnl the usual two ACTION-IF-FOUND / ACTION-IF-NOT-FOUND are supported
+dnl and they can take advantage of the LIBS/CFLAGS additions.
