=head1 NAME |
| 15 |
+ |
|
| 16 |
+ |
Cache::Cache - A generic directory cache object. |
| 17 |

=head1 SYNOPSIS |

=head1 DESCRIPTION |
| 23 |
+ |
|
| 24 |
+ |
A package to provide caching of directory information. Directory timestamps |
| 25 |
+ |
are tracked on further reading of an existing cache and lists of modified |
| 26 |
+ |
directories and BuildFiles can be obtained. |
