I did it this way to avoid touching the CouchDB code, and not wanting  
to impose another file format or do parsing in shell script.  
Especially given that I have an imminent requirement for CouchDB/Win32  
where the shell is complete shit. OTOH I may have to replace the start  
script with C for that reason.

It might be better to have an erlang plugin manager that can deal with  
plugin selection, dependencies and ordering requirements, but that's a  
more intrusive solution.
