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 "/.". | |
