Single MP3s in Root Folder

[slandells]

Single MP3s in the root of the 'original' folder copy to 'mp3merge' folder but then somehow pickup the 'original' folder when checking for folders, so it creates an 'original.m4b' file.
Muiltiple MP3s from different books or the same book all get merged as chapters into one 'original.m4b' file

Is there something no working quite right causing it to pickup the top level folder, or will it always do this if the files aren't in their own folder structure inside the 'original' folder?

At the moment the script is designed that there is one of the following structures:
/original/Author/Book/Chapter-1.mp3
or
/original/Book/Chapter-1.mp3

As somehow the name of the book needs to be determined.
That the book is afterwards called original is obvious a bug and is caused by my method of stripping the book name.

I think I will make a quick workaround to prohibit it.
