Description:

This module is used to check the portability across operating systems
of the names of the files present in the distribution of a module. The
tests use the advices given in perlport/"Files and Filesystems". The
author of a distribution can select which tests to execute.

To use this module, simply copy the code from the synopsis in a test
file named t/portfs.t for example, and add it to your MANIFEST. You
can delete the call to options() to enable only most common tests.

By default, not all tests are enabled because some are judged too
cumbersome to be practical, especially since some of the most limited
platforms (like MS-DOS) seem to be no longer supported.
