-### 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 is implied when running in CI_package_check, you can manually add it if you are manually testing the app.
-### Use the execution time displayed in the CI report or by adding --time to the command, 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 durationt 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"
