Subject: First commit of _InputXSLT_ * quick and dirty proof-of-concept for
 adding plain-file access to XSLT ** based on Apache Xalan XSLT processor *
 The idea is to create something like a static counterpart to Symphony CMS *
 Adding functions to XSLT for file system, plain file and binary file
 (read)-access * This project aims to test how such functionality can be
 integrated into XSLT ** if it works it could be developed into a nice static
 content transformation system * Contrary to the popular opinion I actually
 like XML and XSLT when used responsibly
