[TYPO3-ect] div/lib extensions

[Elmar Hinz]

Hi Ernesto,

I still haven't implemented your proposals, yet. My first target was to get
the library into SVN so that people can do direct improvements. Well, SVN
is done now.

svn ls https://svn.sourceforge.net/svnroot/typo3xdev/tx_lib
svn ls https://svn.sourceforge.net/svnroot/typo3xdev/tx_div
svn ls https://svn.sourceforge.net/svnroot/typo3xdev/tx_articles

Maybe you find a way to fix the source directly. Else I will do that during
 my next working cycle.

Regards

Elmar
