=head1 NAME

File::Spec::Epoc - methods for Epoc file specs

=head1 SYNOPSIS

 require File::Spec::Epoc; # Done internally by File::Spec if needed

=head1 DESCRIPTION

See File::Spec::Unix for a documentation of the methods provided
there. This package overrides the implementation of these methods, not
the semantics.

This package is still work in progress ;-)
