(or a few notes on how to actually use cvs on drupal)

• Intro
• RTFM

• checking out 4.6.4 or 4.7:

zcvs co -rDRUPAL-4-6-4 drupal
zcvs co -rDRUPAL-4-7 drupal

* the newly checked-out version will be available after a

cd drupal

• diff-ing our checked-out, then modified version with 4-6-4:

zcvs diff -rDRUPAL-4-6-4

• building a patch:

cd drupal; 
zcvs diff -up > mychanges.patch

• zcvs is a 3-line script that just does this:

  set CMD="e:\Program Files\Zend\ZendStudioClient-5.0.0\bin\SourceControl\cvs\cvs.exe"
  set ACCESS=-d:pserver:anonymous:anonymous@cvs.drupal.org:/cvs/drupal
  %CMD% %ACCESS% %*

• when patching the database,
  • create a function in updates.inc to update existing files
  • diff the database\database.<engine> files used for initial site creation
