Hello Sébastien, thanks for the awesome script! I am planning to use this A LOT.
However I have a slight problem with it - I would like to use your script as a dependency as well. That means that I need to put your script inside a folder and make it work from there.
I am fine with simple PHP script that would sit in the root of
mu-pluginsfolder and require your plugin (every other plugin will be "autoloaded" by yours).I tried to tweak your code to meet my requirement, but to be honest, I got a little lost in it (mainly due to my lack of knowledge about WP transients).
Would you be kind enough to guide me to some direction? Thanks in advance, P!
