USING TYPO3 FROM SUBVERSION REPOSITORY
=======================================

About global extensions:
 Starting with version 4.0 of TYPO3 the directory typo3/ext/ is considered
 locally composed and maintained. This means you can put a custom
 collection of extensions here which you will have to maintain
 independently of TYPO3core. Some of the old global extensions have been
 moved to be system extensions for your convenience.

 Notice that individual extensions might in fact have their own CVS/SVN
 project somewhere, like on SourceForge.net, project "TYPO3 Extension
 Development Platform" (typo3xdev).

Important post-checklist:
 Follow this list IMMEDIATELY after updating sources from SVN (both core
 and extensions):

 - Update database: In the Install Tool, click "COMPARE" for "Update
   required tables" in "Database Analysis" section. You might dump the
   static tables as well, but less likely to be important
 - "Clear temp_CACHED" files from "typo3conf/" of your sites
 - "Clear FE Cache"
 - Using PHP-accelerator or other PHP cache? If you fatal PHP-errors,
   always remove the cached files (eg. "/tmp/phpa_*"), restart Apache and
   try again.

 (Hint: Take a look at "misc/superadmin.php" script which will greatly
 help you to maintain multiple TYPO3 installations when updating)

Committing changes to the core:
 This is only allowed for members of the core team [1] who are also having
 "developer" status on SourceForge [2].

 There is defined a set of rules and conditions under which to commit to
 the core SVN. These are found in "misc/core_svn_rules.txt".

For more questions, please refer to [3].
