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