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 ;-) |

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