### 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"

### `ynh_install_app_dependencies` allows you to add any "apt" dependencies to the package.
### Those deb packages will be installed as dependencies of this package.
### If you're not using this helper:
###		- Remove the section "REMOVE DEPENDENCIES" in the remove script
###		- Remove the variable "pkg_dependencies" in _common.sh

### The password will be stored as 'mysqlpwd' into the app settings,
### and will be available as $db_pwd
### If you're not using these lines:
###		- Remove the section "BACKUP THE MYSQL DATABASE" in the backup script
