need clarification on various PSL1GHT forks

i've been recently properly confused about which psl1ght to use. different homebrew wants different psl1ight which is arranged in a different way after installation.

some psl1ght builds have different headers/libraries and require fixing up of build scripts (or looking for the right psl1ght fork).

can somebody point me towards the most official psl1ght source most homebrew developers use? why isn't it developed as a single project?

i mostly try to stick to one provided by ps3toolchain buildscript, as it appears to be most actively maintained, and lots of extra dev libraries build against it.
