I'm new here and don't know if this is relevant. I just thought I'd
mention that you should be careful with the concept of a 'dirsep' as a way
of making paths cross platform.
Sun tried to make their paths general by using a 'dirsep' in java. This
never really worked. It allowed some simple translation between DOS and
Unix paths, but some more complex cases failed. Under MacOS (pre-X) it was
such a disaster that apple just moved to using Unix paths in java rather
than MacOS paths.
examples: On MacOS relative paths start with filesep whereas under Unix
absolute paths do. On MacOS there is no '..' for the parent directory;
that case is handled by two dirseps in a row.
Two ways around this are:
i) Use unix paths. This standardizes the semantics.
ii) Use URLs. This also standardizes the semantics and is probably the
