# DESCRIPTION |
| 6 |
|
|
# |
| 7 |
|
|
# This library defines a BackupPC::View class for merging of |
| 8 |
|
|
# incremental backups and file attributes. This provides the |
| 9 |
|
|
# caller with a single view of a merged backup, without worrying |
| 10 |
|
|
# about which backup contributes which files. |
