Instiki users - Oct 2005 - [Instiki] possible to enable file upload in version 0.10.2?

I would like to play with the file upload feature.  As I understand  
it, it exists, but is disabled by default in version 0.10.2.  I  
obtained the 0.10.2 source via svn (svn co http://svn.instiki.org/ 
instiki/trunk instiki).  Can I simply enable file uploads?  Thanks.
