Last change on this file since 9f12e36 was 9f12e36, checked in by Randy McMurchy <randy@…>, 18 years ago

Removed 'keywordset' blocks and extra spaces from the XML files (note this was by accident as I meant to do just in the gnome directory but I was in the root of BOOK when I ran the script, but this was going to happen anyway so I don't think it is a big deal)

94 use additional software such as a database back-end for virtual users, or
