+#
+# To use gem or Go, use the alias `ynh_gem` and `ynh_go`
+# 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_go`
+# And propagate $PATH to sudo with $ynh_go_load_path
+# Exemple: `ynh_exec_as $app $ynh_go_load_path $ynh_gem install`
+#
+# $PATH contains the path of the requested version of Go.
+# However, $PATH is duplicated into $go_path to outlast any manipulation of $PATH
+# You can use the variable `$ynh_go_load_path` to quickly load your Go version
+#  in $PATH for an usage into a separate script.
+# Exemple: $ynh_go_load_path $final_path/script_that_use_gem.sh`
+#
+#
+# Finally, to start a Go service with the correct version, 2 solutions
+#  Either the app is dependent of Go or gem, but does not called it directly.
+#  In such situation, you need to load PATH

+#  Or Go start the app directly, then you don't need to load the PATH variable
