 # FUTUR OFFICIAL HELPERS
 #=================================================
 
-# Internal helper design to allow helpers to use getopts to manage their arguments
-#
-# [internal]
-#
-# example: function my_helper()
-# {
-#     declare -Ar args_array=( [a]=arg1= [b]=arg2= [c]=arg3 )
-#     local arg1
-#     local arg2
-#     local arg3
-#     ynh_handle_getopts_args "$@"
-#
-#     [...]
-# }
-# my_helper --arg1 "val1" -b val2 -c
-#
-# usage: ynh_handle_getopts_args "$@"
-# | arg: $@    - Simply "$@" to tranfert all the positionnal arguments to the function
-#
-# This helper need an array, named "args_array" with all the arguments used by the helper
-# 	that want to use ynh_handle_getopts_args
-# Be carreful, this array has to be an associative array, as the following example:
-# declare -Ar args_array=( [a]=arg1 [b]=arg2= [c]=arg3 )
-# Let's explain this array:
-# a, b and c are short options, -a, -b and -c
-# arg1, arg2 and arg3 are the long options associated to the previous short ones. --arg1, --arg2 and --arg3
-# For each option, a short and long version has to be defined.
-# Let's see something more significant
-# declare -Ar args_array=( [u]=user [f]=finalpath= [d]=database )
-#
-# NB: Because we're using 'declare' without -g, the array will be declared as a local variable.
-#
-# Please keep in mind that the long option will be used as a variable to store the values for this option.
-# For the previous example, that means that $finalpath will be fill with the value given as argument for this option.
-#
-# Also, in the previous example, finalpath has a '=' at the end. That means this option need a value.
-# So, the helper has to be call with --finalpath /final/path, --finalpath=/final/path or -f /final/path, the variable $finalpath will get the value /final/path
-# If there's many values for an option, -f /final /path, the value will be separated by a ';' $finalpath=/final;/path
-# For an option without value, like --user in the example, the helper can be called only with --user or -u. $user will then get the value 1.
-#
-# To keep a retrocompatibility, a package can still call a helper, using getopts, with positional arguments.
-# The "legacy mode" will manage the positional arguments and fill the variable in the same order than they are given in $args_array.
-# e.g. for `my_helper "val1" val2`, arg1 will be filled with val1, and arg2 with val2.
