 #!/bin/bash

-# Probably called from a /usr/share/xsessions/somesession.desktop that lists an
-# exec like dwm.custom, and the dwm.custom executable script looks like:
-#
-# #!/bin/bash
-#
-# if [ -f "$HOME/.dwmrc" ]; then
-#     exec "$HOME/.dwmrc"
-# else
-#     exec dwm.custom
-# fi
+# Startup on my Ubuntu 14.04 system works like this:
+# - lightdm finds /usr/share/xsessions/dwm.desktop
+# - This desktop file launches dwm.user, which is found in /usr/bin
+# - /usr/bin/dwm.user is a script that execs $HOME/.dwmrc, if present, else it
+#   execs dwm.
+# - This is my dwmrc, which installs as ~/.dwmrc
 
 # Although the system startup merged ~/.Xresources, it did so with the -nocpp
 # option (Ubuntu 14.04), which prevents the use of #define, etc.  Re-merge here
