+createindex
+===========
+Creates a nice index of your collection, similar to what oidua
+(http://oidua.suxbad.com/) does, but much faster, as it is using AtOM's DB
+instead of rescanning your whole collection.
+
+Options define what will be shown and may optionnally be followed by the column
+width (default: 50).
+
+Options:
+	-f:	Path
+	-b:	Average bitrate
+	-C:	Channels
+	-s:	Sample rate
+	-T:	Mofification time
+
+	-A:	Album artist
+	-l:	Album
+	-a:	Artist
+	-c:	Composer
+	-d:	Disc
+	-g:	Genre
+	-p:	Performer
+	-t:	Title
+	-y:	Year
+
+	-d <format>:	date-time format (see 'man date' for possible values)
+	-o -|<file>:	output file (path relative to Source) - mandatory - must
+			appear last.
