Why this empty line?

Please move regexdev after [compress].

Why adding it at the end?
I would suggest adding regexdev after compressdev.

Please remove the _lib suffix in this filename.

Please avoid empty line at end of files.

strange choice :)
I would have added regex at the end of the previous line which is shorter.
