My family uses 1.3.6 on three Ubuntu 6.06 LTS boxes for books, articles, reports, Broadway, and classroom materials. I've home built 1.5.2 for Ubuntu Feisty for testing. Have not decided to upgrade the rest yet but will test 1.5.3 soon.
An open-source project that I work with, the Enhanced Machine Controller also uses 1.3.6 extensively for documentation. Lyx files are included in the CVS for the project. We offer the option of automatic document preparation during make and provide automated updates if changes are made to the lyx code for the developer versions of documents on our site. That documentation runs several hundred pages of PDF and quite a stack of HTML. The curious can browse/download at http://www.linuxcnc.org/docs/devel/. Really intrepid explorers are welcome at http://cvs.linuxcnc.org/cvs/emc2/docs/src/ Thanks to all for a great product, great service, and really quick help. Ray Henry
