+# Requirements: xpra, xvfb, ratpoison, firejail
+#
+# Simpler design: simply run ratpoison using xpra
+# xplex attach <session> # create a session if does not exit
+# xplex detach <session>
+#
+# Complex design:
+# xplex run    <session> <command>
+# xplex attach <session>
+# xplex detach <session>
