User guide contributions
bocrelolo Contributions to the guide would be great. Please, please make some!
For small corrections such as typos, spelling, grammar, and factual in-accuracies please email the author. For larger contributions - additional chapters, translations and so on, please consider using LyX to edit the document source and submit patches to the author.
Getting the document source
The source for the user guide is available by anonymous SVN from the sourceforge project pages.
You can get LyX from the LyX website. You can use the latest stable release of LyX (1.5.1) to edit the .lyx files that make up the user guide.
Submitting a patch
Once you've got LyX and the guide source, edit the files and make a patch file using diff. You can find a nice tutorial about how to do this here.
Patches should be emailed to the guide author
