| 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 ;-) |

| 38 | |
| 39 | No physical check on the filesystem, but a logical cleanup of a |
| 40 | path. On UNIX eliminated successive slashes and successive "/.". |
