This little script sends it's command line arguments as a query to the online dictionary at http://dict.leo.org and writes the parsed result to stdout. It uses Tcl's http package and the htmlparse and ncgi packages from Tcllib.
The scraper part (everything inside the ::dict.leo.org namespace) could also be included from other frontends. It's [query] proc takes a list of words to search for, and returns a list of english/german pairs that matched the query.

Richard Suchenwirth comments: Proud owners of a firewall might have to add a line like http::config -proxyhost proxy -proxyport 80
at the very top of proc query. Helped in my case to really get out.
