+# Load the version of Ruby for an app, and set variables.
+#
+# 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 $final_path/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_ENV_PATH__"`
+#    `ExecStart=__FINALPATH__/my_app`
+#     You will replace __YNH_RUBY_LOAD_ENV_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
+#   - $ruby_path: The absolute path to Ruby binaries for the chosen version.
