URL to walk

A URL to an HTML page to put into the todo list. It should be a fully qualified URL such as http://www.mysite.com or http://www.mysite.com/docs/widget.html.

You may specify a collection of URLs by placing them in a file, one per line, and specifying the filename preceded by & instead of a URL. Place quotes (") around it on the command line since & is special to the command shell.

e.g.: ``gw "&url.lst"'' will read a list of URLs from the file url.lst.

gw can also read the list from its standard input (a pipe). Just use - instead of the filename.

e.g.: ``findurl | gw "&-"'' will read a list of URLs from the output of the fictional command findurl.
