According to yelp(1), yelp can be called with a file argument. This does not work though. When I run "yelp gnumeric.xml" (in a directory that indeed has a gnumeric.xml in it), I get an error popup: Unable to load page The requested URI "gnumeric.xml" is invalid. Yelp does accept a URI argument though: "yelp file:/$(pwd)/gnumeric.xml" shows the documentation. Please update the manpage to reflect this.
