#    DEV_MODE=1
#      Will start the Theia IDE in the background, regular Odoo commands will still work.
#      Note that in Theia you can re-start Odoo e.g.
#        `kill -s SIGHUP 1` to reload/restart Odoo
#        `kill -s SIGQUIT 1` to cause Odoo to dump stacktrace in standard out
#      Note that with Odoo running in the foreground, killing Odoo will kill the container.
#    DEV_MODE=
#      Unset to not use Theia at all.
#    
#    DEV_MODE_PATH=/opt/odoo/addons
#      To change the path to start Theia in, useful to get git working.
