+Display Manager Scriptlets HOWTO
+================================
+
+To keep display manager specific code out of the generic
+start script (/etc/init.d/xdm) as much as possible display
+managers should provide a script file that provides anything
+specific to this dm.
+
+At minimum the script file needs to provide:
+here <DM> denotes the name of the file. This should
+be the same as the pid file generated by the display
+manager - without the .pid extent.
+
+# this function matches the command line argument. If it
+finds a match it initializes any dm specific variables
+and returns 0 (success) otherwise it returns 1 (fail).
+At minimum it needs to set the full path the the display
+manager binary.
+It may set STARTPROC to a function that gets run prior to
+starting a dm, RELOADPROC to a function that's run to reload
+the DM configuration, PROBEPROC to a function that's run
+when the DM status is probed.
+Any those functions should return 0 on success or any other
+value on failure.
+Additionally it may initialize any other variables needed
+by the DM.
