This is the source code repository for RE2, a regular expression library.
For documentation about how to install and use RE2,
visit https://github.com/google/re2/.
The short version is:
make
make test
make install
make testinstall
There is a fair amount of documentation (including code snippets) in
the re2.h header file.
