Thanks Rhys, I had not thought about other directory builds. I will add that to the todo list for next time :)

I've not looked at the Sphinx docs before. They're pretty. Does not work from a VPATH build (i.e. unpack GSL sources, run autogen.sh, create a wholly separate directory, then run GSL's configure from inside that separate directory). In particular, with messages... make[1]: Leaving directory '/home/rhys/Build/gsl-gcc/doc/examples' Error: Config directory doesn't contain a conf.py file. VPATH building of documentation is an edge case. Likely not worth pursuing a fix at all and certainly not worth holding up 2.6. I just tried it because I tend to use VPATH for autoconfiscated projects. - Rhys
