+# makedesc directory file

+# Scan the directory for files, and use the files to generate a task
+# description file. The format of the task description file is described in
+# data.c. The format of the input files is:
+#
+# Task: desktop
+# Description: Provide a basic GUI system
+#  This task provides functionality for a basic desktop; whether Gnome
+#   based, KDE based or customised. With this task, your system will boot
+#   into a graphical login screen, at which point you can choose which of
+#   these desktops you wish to use on a per-user basis. You can further
+#   customise your desktop once installed.
+# Packages-list:
+#  kdebase
+#  gdm
+#  ...
+#
+# Hash-comments are allowed in the files, but must be on their own lines.
