SUSv4, c99, LP64, dubious glances at the Linux man pages, and beyond
that stay simple and wing it.

I note that I may wind up _writing_ a spec for a mount command, because
there isn't one.  I've looked.

What license is your new library under?

Bionic actually looks... almost sane.  Toolbox is a joke but bionic
might be worth extending.  Dunno.

In theory if you clone the android open source project there's a bionic
subdirectory.  That's where I got the copy I was looking at at work.
Alas, the android guys aren't big into DOCUMENTING what they're doing,
so reading the code is pretty much it apparently...
