+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description. Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in. You must
+# make exactly 11 lines for the formatting to be correct. It's also
+# customary to leave one space after the ':'.

+sddm: sddm (QML based X11 display manager)
+sddm:
+sddm: SDDM is a modern display manager for X11 aiming to be fast, simple and
+sddm: beautiful. It uses modern technologies like QtQuick, which in turn
+sddm: gives the designer the ability to create smooth, animated user
+sddm: interfaces. SDDM is extremely themeable. There are a few sample themes
+sddm: distributed with SDDM. They can be used as a starting point for new
+sddm: themes.
