+# backupninja handler to do incremental backups using
+# wget and hardlinks, based on rsync handler
+#
+# feedback: rhatto at riseup.net | gpl
+# lot of enhancements grabbed from "rsnap" handler by paulv at bikkel.org
+#
+# Config file options
+# -------------------
+#
+#   [general]
+#   log = wget log file
+#   partition = partition where the backup lives
+#   fscheck = set to 1 if fsck should run on $partition after the backup is made
+#   read_only = set to 1 if $partition is mounted read-only
+#   mountpoint = backup partition mountpoint or backup main folder
+#   backupdir = folder relative do $mountpoint where the backup should be stored
+#   days = number of backup increments (min = 5)
+#   lockfile = lockfile to be kept during backup execution
+#   nicelevel = wget command nice level
+#   enable_mv_timestamp_bug = set to "yes" if your system isnt handling timestamps correctly
+#   tmp = temp folder
+#
+#   [source]
+#   wget = wget program
+#   wget_options = wget command options
+#   url = remote data url
+#   bandwidthlimit = set a badnwidth limit in kbps (remote source only)
+#
+#   [destination]
+#   folder = local folder
+#
+# You can also specify some system comands if you don't want the default system values:
+#
+#   [system]
+#   rm = rm command
+#   cp = cp command
+#   touch = touch command
+#   mv = mv command
+#   fsck = fsck command
