## usage zotonic.sh {debug|start|stop|restart}
##
## Use "debug" to start an interactive shell (highly recommended when installing the db on the first run).
## Use "start" in production. This boots zotonic in an erlang vm with a heart beat process.
##
## The proposed directory structure is:
## /home/zotonic/zotonic.sh                         -- this script
## /home/zotonic/zotonic/...                        -- the zotonic code
## /home/zotonic/zotonic/priv/sites/default/...     -- your site and uploaded files go here

# Change this to your base directory
BASE=/home/zotonic

# Change this to the complete path to zotonic.sh (this script)
ZOTONIC_SH=$BASE/zotonic.sh

# Change this to the directory where you have unpacked zotonic
# IMPORTANT: this directory must be called zotonic or zotonic-x.y where x.y is the version number.
ZOTONIC=$BASE/zotonic

# Change this to point to the erlang vm
ERL="/usr/local/bin/erl"

# The include path for the erlang vm, add when needed for your application.
PA="$ZOTONIC/ebin $ZOTONIC/deps/*/ebin $ZOTONIC/modules/*/deps/*/ebin $ZOTONIC/priv/modules/*/deps/*/ebin $ZOTONIC/priv/sites/*/modules/*/deps/*/ebin"

# The name of the Erlang node, this must be unique on your host.
SNAME=zotonic001

# Set the hostname to the fully qualified domain name of your host, or leave it as localhost.
# HOSTNAME=`hostname`
# HOSTNAME=your.domain.com
HOSTNAME=localhost

# The command used to restart zotonic when crashed, only used after a "zotonic.sh start"
export HEART_COMMAND="$ZOTONIC_SH start"

## The port and IP address zotonic will bind to (defaults to all ip addresses and port 8000)
export ZOTONIC_IP=any
export ZOTONIC_PORT=8000

# The filename where zotonic writes its unix process Id to, for monitoring applications.
