Me too and I'm sure we're not the only ones. But look at this quote from the article:
> surely no one competent would choose to have a package depend on `which` when a standard POSIX utility can do a better job
This is an mind-bogglingly misguided attitude. Anyone that has never heard of an obscure POSIX command is incompetent? Or is it that really that most people don't want to spend their time writing awful shell scripts and figuring out exactly what is POSIX and what isn't?
