Where's the goodies?

[Darren New <dnew@san.rr.com>]

I'm playing with GNAT on Win2K. I've heard mentions of regexp libraries
and such. What I'll definitely need is byte-oriented I/O to files and
sockets (i.e., raw binary files), as well as access to directories and
things like that. I'll need GUI too, but I haven't decided whether to do
that with the Tcl interface, the GTK interface, or with an external
program talking via sockets. 

My question is, where's the goodies? These things have to be out there,
but there's no documentation about them in the GNAT distribution that
I'm seeing. Am I missing it? Have I failed to download the right
programs? Is it deep in the bowels of AdaPower where searches for
obvious keywords fail to turn them up? (I get two sockets libraries from
a search, one of which is inaccessible, the other of which looks pretty
good.) 

I guess my real question is, "what comes with GNAT, and why can't I find
it?" :-)

TIA for any clues for the clueless.
