Right.

Yeah. That feature will currently fail when the rebar configuration uses 
hooks, scripts and such. It's good for 90% of projects but this one is 
too complex.

Yaws is fine.

Autotools support is something I have been meaning to add (both 
compiling projects that use autoconf and erlang.mk being usable in a 
larger autotools build environment). There are one or two projects I 
want to write plugins for that use autotools (I believe percept2 is one 
of them).

Please add a ticket so I can look into it (I can't seem to be able to 
load Github this morning). I will work on an update this or next week so 
I could do it then.

Cheers,
