Testing
=======
After running make as given above you can run:
make test
This will generate some data files from /usr/bin /usr/share and
/usr/include directories and then run a whole lot of tests. These
execute pcompress with a wide variety of combinations of options.
For every test both compression and decompression are performed
and after every decompression the decompressed file is verified
byte for byte with the original using the diff utility.
It takes a while to run all the tests.
