Yes, the validator was written with CGI in mind, and even though we've
been working a lot on making the codebase cleaner (remove inline HTML,
etc), it is still very much a cgi in the way it works. it does not,
however, depend too much on apache, and it *can* be used from the
commandline, e.g:

validator/httpd/cgi-bin% ./check uri=http://www.w3.org output=n3
Content-Type: text/plain; charset=UTF-8
X-W3C-Validator-Status: Valid
X-W3C-Validator-Errors: 0

Also, note that although the validator does quite a lot of parsing and 
processing, it is *mostly* a wrapper around openSP+an SGML+xml 
catalogue, made to present results in a "nice" way.  And openSP can run 
from the command line...

I can not think of a commandline tool right now (possibly because 
opensp mostly fills that role), but I've seen an IE bar and a windows 
desktop tool both (AFAIK) based on some version of SP, and developed by 
people on this list...

Hope this helps.
