For standalone w3c validator

Hello,

Sorry to bother the whole list.
I am a M.S. student in Tsinghua University, P.R.China.
Currently I am trying to make a large scale web page validation
to find out the degree to which the web pages in China are validated
against an HTML DTD, such as HTML 4.01. I have noticed that the w3c
validator can be run as a local CGI service. However, it would be much 
quicker if the files can be checked standalone instead of being put
through the CGI of a web server. Is there a command-like version of
w3c validator, which can be configured by a config file or command
options? 
Thank you.

Sincerely,
Shaozhi
