| 12 | ||
| 13 | File::Spec::Epoc - methods for Epoc file specs | |
| 14 | ||
| 15 | =head1 SYNOPSIS | |
| 16 | ||
| 17 | require File::Spec::Epoc; # Done internally by File::Spec if needed | |
| 18 | ||
| 19 | =head1 DESCRIPTION | |
| 20 | ||
| 21 | See File::Spec::Unix for a documentation of the methods provided | |
| 22 | there. This package overrides the implementation of these methods, not | |
| 23 | the semantics. | |
| 24 | ||
| 25 | This package is still work in progress ;-) | |

| 37 | No physical check on the filesystem, but a logical cleanup of a | |
| 38 | path. On UNIX eliminated successive slashes and successive "/.". | |
