-### 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.
