I am having some trouble with jscalendar and the views date module, so I want to make sure I have the "latest cvs version" (of the DRUPAL-5 branch!).
This also shows how to set up a whole site with spanking new stable branch code. Source: Drupal Handbook page .
First check out Drupal itself:
cvs -d:pserver:anonymous:firstname.lastname@example.org:/cvs/drupal checkout -r DRUPAL-5 -d mysite drupal
Then check out any modules you want (actually, should put them in ./sites all, but this is just an example, here I am the date module in ./modules/date)
cvs -d:pserver:anonymous:email@example.com:/cvs/drupal checkout -r DRUPAL-5 -d mysite/modules/date contributions/modules/date
