The "Strip Key prefix" part is confusing to me.
"Strip Key Prefix"
makes no sense as it strips the first word of the String and not of the KEY in the example provided.
I suggest also the overlib to be clarified with an example (make artifact?).
Other remark concerning: " Language files loaded. A list of all the language files loaded in the process of building the page, including full path information. This can be useful to check that the expected files have been loaded. The number after each file path is the number of times that the file was referenced. "
I suggest adding there that no number means that the ini file is not present and therefore could not be loaded.
