-#
-# ynh_use_ruby has to be used in any app scripts before using Ruby for the first time.
-# This helper will provide alias and variables to use in your scripts.
-#
-# To use gem or Ruby, use the alias `ynh_gem` and `ynh_ruby`
-# Those alias will use the correct version installed for the app
-# For example: use `ynh_gem install` instead of `gem install`
-#
-# With `sudo` or `ynh_exec_as`, use instead the fallback variables `$ynh_gem` and `$ynh_ruby`
-# And propagate $PATH to sudo with $ynh_ruby_load_path
-# Exemple: `ynh_exec_as $app $ynh_ruby_load_path $ynh_gem install`
-#
-# $PATH contains the path of the requested version of Ruby.
-# However, $PATH is duplicated into $ruby_path to outlast any manipulation of $PATH
-# You can use the variable `$ynh_ruby_load_path` to quickly load your Ruby version
-#  in $PATH for an usage into a separate script.
-# Exemple: $ynh_ruby_load_path $install_dir/script_that_use_gem.sh`
-#
-#
-# Finally, to start a Ruby service with the correct version, 2 solutions
-#  Either the app is dependent of Ruby or gem, but does not called it directly.
-#  In such situation, you need to load PATH
-#    `Environment="__YNH_RUBY_LOAD_PATH__"`
-#    `ExecStart=__FINALPATH__/my_app`
-#     You will replace __YNH_RUBY_LOAD_PATH__ with $ynh_ruby_load_path
-#
-#  Or Ruby start the app directly, then you don't need to load the PATH variable
-#    `ExecStart=__YNH_RUBY__ my_app run`
-#     You will replace __YNH_RUBY__ with $ynh_ruby
-#
-#
-# one other variable is also available
