+ejabberd is an open-source, robust, scalable and extensible realtime
+platform built using Erlang/OTP, that includes XMPP server, MQTT broker
+and SIP service.
+
+A user and group "ejabberd" must exist prior to running this script.
+To create them run as root:
+  groupadd -g 370 ejabberd
+  useradd -u 370 -g 370 -s /sbin/nologin -d /var/lib/ejabberd ejabberd
+
+You can enable the following optional features by passing variables to
+the script (VAR=yes ejabberd.SlackBuild):
+
+ODBC=yes|no (default: no), enable ODBC support
+MYSQL=yes|no (default: no), enable MySQL support
+PGSQL=yes|no (default: no), enable PostgreSQL support
+SQLITE=yes|no (default: no), enable SQLite support
+PAM=yes|no (default: no), enable PAM authentication
+REDIS=yes|no (default: no), enable Redis support
+ELIXIR=yes|no (default: no), enable Elixir support
+SIP=yes|no (default: no), enable SIP support
+LUA=yes|no (default: no), enable Lua support (to import from Prosody)
+TOOLS=yes|no (default: no), build development tools

+# 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 ':' except on otherwise blank lines.
