-# Curl abstraction to help with POST requests to local pages (such as installation forms)
-# For multiple calls, cookies are persisted between each call for the same app
-#
-# $domain and $path_url should be defined externally (and correspond to the domain.tld and the /path (of the app?))
-#
-# example: ynh_local_curl "/install.php?installButton" "foo=$var1" "bar=$var2"
-#
-# usage: ynh_local_curl "page_uri" "key1=value1" "key2=value2" ...
-# | arg: page_uri    - Path (relative to $path_url) of the page where POST data will be sent
-# | arg: key1=value1 - (Optionnal) POST key and corresponding value
-# | arg: key2=value2 - (Optionnal) Another POST key and corresponding value
-# | arg: ...         - (Optionnal) More POST keys and values
-#
-# Requires YunoHost version 2.6.4 or higher.
