There are many ways to help out with PHPee.com projects. If you're not a developer you can submit bug reports or feature suggestions. When doing this please make sure to include all the information you can while reporting, including: Operating System, PHP version, and project version. Also include any files your having problems generating docs from.
You might also want to checkout the other information on the SourceForge project pages.
You can obtain a current copy of the source code of each project using CVS. Here is how to check out the latest HEAD:
$> cvs -d :pserver:firstname.lastname@example.org:/repository login
$> cvs -z3 -d :pserver:email@example.com:/repository co modulename
...whereas modulename is one of the following: sourdough, pigalle, yabook, pphlogger
Note: If you get an error from cvs when using the login command (cvs login: warning: failed to open /username/.cvspass for reading: No such file or directory) then repeat the login command.
If you already have an existing version of any module and want to update:
$> cd <your module directory>
$> cvs -z3 -d :pserver:firstname.lastname@example.org:/repository update -APd
For Windows users, there are a number of graphical CVS clients available such as the very capable and easy-to-use TortoiseCVS. You should also try a current beta version of WinCVS.
