+# Evennia init.d Screen launcher script (Linux)
+#
+# This requires a Linux using init.d. I is used togeter
+# with the evennia-screen.sh script, which must be working
+# before setting this one up. This script is meant to be
+# used as part of Linux' automatic services and requires
+# root to set up.
+#
+# Usage:
+#  1. sudo cp evennia-screen-initd.sh /etc/init.d/evennia
+#  2. cd /etc/init.d
+#  3. Edit this script (now renamed to 'evennia') and
+#     change SCRIPTPATH and USER below to fit your setup.
+#  4. sudo chown root:root evennia
+#  5. sudo chmod 755 evennia
+#
+# You can now use (as root) ´services evennia start|stop|reload`
+# to operate the server. The server will run as the USER you
+# specify and must thus have access to start the server 
+# (*don't* set it to run as root!).
+#
+# To make Evennia auto-start when the server reboots, run
+# the following:
+#
+#    sudo update-rc.d evennia defaults 91
+#
+
+
+# CHANGE to fit your setup (obs: no spaces around the '=')

+# GNU Screen bash startup script (Linux only)
+#
+# This script is meant for auto-restarting Evennia on a Linux server
+# with the standard GNU Screen program installed. Evennia will be
+# launched inside a detached Screen session, you can then connect
+# to with screen -r <gamename>. This will make sure that the
+# runner reload process is not killed when logging out of the server.
+# A Screen session also has the advantage that one can connect to it
+# and operate normally on the server after the fact.
+#
+# Usage:
+#
+# 1. First make sure Evennia can be started manually.
+# 2. Copy this script to mygame/server.
+# 3. Edit the GAMENAME, VIRTUALENV and GAMEDIR vars below to
+#    match your game.
+# 4. Make it executable with 'chmod u+x evennia-screen.sh'.
+#
+# See also evennia-screen-initd.sh for auto-starting evennia
+# on the server.
