fix run_BackupPC_nightly to detect install/bin directories
usage="
Usage: $0 [-c [-d -b -r [-f]] | [-l]] | [-n]
Delete specified client backups.
Options:
-c - client machine for which the backup was made
-d - number of Backup which should be deleted
-b - delete all backups before this date (YYYY-MM-DD)
-r - remove the entire client
-f - force to run Backuppc_nightly so the space got free afterwards
-n - only run Backuppc_nightly
-l - list the backups which made for
-n - Just run BackupPC_nightly (even if no backups deleted)
-h - this help
