To use ReTest, you will need to have the following software packages installed: 1) Perl - this should already be installed on most operating systems. For Windows you can get it from http://activestate.com/. Then, you need to build and install ReTest itself: perl Makefile.PL make make test # optional, as superuser: make install Now you should be able to run it as 'retest SRCDIR PUBLISHDIR' and it will use the source files in SRCDIR to generate final tests into PUBLISHDIR.
