Please write web pages about your package for installation on
www.gnu.org. They should follow our usual standards for web
pages (see http://www.gnu.org/server/fsf-html-style-sheet.html).
The overall goals are to support a wide variety of browsers, to focus
on information rather than flashy eye candy, and to keep the site
simple and uniform.
Some GNU packages have just simple web pages, but the more information
you provide, the better. So please write as much as you usefully can,
and put all of it on www.gnu.org. However, pages that access
databases (including mail logs and bug tracking) are an exception; set
them up on whatever site is convenient for you, and make the pages on
www.gnu.org link to that site.
