libiberty docs are in

[DJ Delorie]

I just checked in preliminary documentation for libiberty.  It is not
built by default; do "make info" or "make dvi" to build it.  Please
report any problems to me (and the usual places, of course ;)

At this time I would like to ask people who either maintain or have
recently contributed to still-undocumented parts of libiberty to
please consider submitting any needed documentation for those parts.
I can help with any editing or integration - even raw docs would help.

Many thanks to Phil Edwards for supplying the initial documentation
files, and for reminding me (many times ;) to get around to this.

Thanks,
DJ
