+# libgnuregex
+
+This library exists because some systems don't have a flavor of regex library
+built-in which supports groups.  This variant does include group-support.  An
+example of where this comes into play is with the `BUrl` class where URLs are
+parsed, in part, using regular expressions.
+
+## Use with MacOS-X
+
+In the case of MacOS-X, the dynamic-library build product
+`libgnuregex_build.so` can be configured for use by configuring the
+`DYLD_INSERT_LIBRARIES` environment variable.
