+# set up namespace for a particular version of doom and launch it
+# default setup:
+# - $home/lib/doom: mntpt and location of config file
+# - $home/lib/doom/$game: user game directories: savegames and screenshots
+# - /sys/games/lib/doom/$game: system iwad and pwad directories
+# cwd is bound over $mntpt to allow loading stuff from there
+# example: launch doom2 with scythe.wad (both in /sys/games/lib/doom/d2)
+# ; doom d2 -file scythe.wad
+# example game version names:
+# doom.wad → /sys/games/lib/doom/d1/
+# doom2.wad → /sys/games/lib/doom/d2/
+# doom2f.wad → /sys/games/lib/doom/d2f/
+# doom1.wad → /sys/games/lib/doom/dsh/
+# plutonia.wad → /sys/games/lib/doom/plt/
+# tnt.wad → /sys/games/lib/doom/tnt/
