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