17 | File::Spec::VMS - methods for VMS file specs |
18 | |
19 | =head1 SYNOPSIS |
20 | |
cbc7acb0 |
21 | require File::Spec::VMS; # Done internally by File::Spec if needed |

23 | =head1 DESCRIPTION |
24 | |
25 | See File::Spec::Unix for a documentation of the methods provided |
26 | there. This package overrides the implementation of these methods, not |
27 | the semantics. |
