### `ynh_use_logrotate` is used to configure a logrotate configuration for the logs of this app.
### Use this helper only if there is effectively a log file for this app.
### If you're not using this helper:
###		- Remove the section "BACKUP LOGROTATE" in the backup script
###		- Remove also the section "REMOVE LOGROTATE CONFIGURATION" in the remove script
###		- As well as the section "RESTORE THE LOGROTATE CONFIGURATION" in the restore script
###		- And the section "SETUP LOGROTATE" in the upgrade script

# ADVERTISE SERVICE IN ADMIN PANEL
#=================================================

### `yunohost service add` is a CLI yunohost command to add a service in the admin panel.
### You'll find the service in the 'services' section of YunoHost admin panel.
### This CLI command would be useless if the app does not have any services (systemd or sysvinit)
### If you're not using these lines:
###		- You can remove these files in conf/.
###		- Remove the section "REMOVE SERVICE FROM ADMIN PANEL" in the remove script
###		- As well as the section "ADVERTISE SERVICE IN ADMIN PANEL" in the restore script

yunohost service add $app --log "/var/log/$app/$app.log"
