### The id of the app as stated in the manifest is available as $YNH_APP_ID
### The instance number is available as $YNH_APP_INSTANCE_NUMBER (equals "1", "2", ...)
### The app instance name is available as $YNH_APP_INSTANCE_NAME

### About --weight and --time
### ynh_script_progression will show to your final users the progression of each scripts.
### In order to do that, --weight will represent the relative time of execution compared to the other steps in the script.
### --time is a packager option, it will show you the execution time since the previous call.
### This option should be removed before releasing your app.
### Use the execution time, given by --time, to estimate the weight of a step.
### A common way to do it is to set a weight equal to the execution time in second +1.
### The execution time is given for the duration since the previous call. So the weight should be applied to this previous call.

### If the app uses nginx as web server (written in HTML/PHP in most cases), the final path should be "/var/www/$app".
### If the app provides an internal web server (or uses another application server such as uwsgi), the final path should be "/opt/yunohost/$app"
