Sven I know what Ston is :)
Now Pillar dev used Ston as input and it works. Then with some hooks they
let the user convert the strings
into specific objects and this is ok.
Now I want to add export in Ston and for configurations I need to control
for the application and not as a ston object the value saved.
For example a file reference should not be just a file reference in Ston
but
a string relative the the baseDirectory of the configuration.
So I thought that I can build a hook and control the call to Ston (convert
the object before to the correct values) and export.
It should be working now doing this I found myself redoing the output of
Ston.
So I will do it. Then I thought that may be I could reuse this logic.
