| 12 | =head1 SYNOPSIS |
| 13 | |
| 14 | B<dh_perms> [S<I<debhelper options>>] |
| 15 | |
| 16 | =head1 DESCRIPTION |
| 17 | |
| 18 | dh_perms is a debhelper program that is responsible for setting the |
| 19 | permissions of files and directories according to the information in |
| 20 | debian/permissions. It is intended to be run after dh_fixperms. |
| 21 | |
| 22 | The file debian/permissions is a tab seperated file where the first column |
| 23 | contains a filename, the second one the permissions in octal format, the |
| 24 | third one the owner and the fourth one the group. A dash in columns 2 to 4 |
| 25 | means that this information will not be modified. |
| 26 | |
| 27 | =head1 OPTIONS |
