README

+This is a remarkably trivial package that makes simply HTML-based presentations from
+a set up source files written using Textile. It's designed to help when creating
+slides that contain lots of code, as it allows code to be embedded from external source files. 
+This means that the code that you embed can come from running (and tested) programs.
+
+The code in the resulting slides is syntax highlighted, and is hyperlinked to the original
+source file, allowing that file to be brought up in Textmate.
+
+To get started
+
+* make sure you have Ruby 1.8.6 installed, along with the Rake and redcloth gems
+* type 'rake all' in the same directory as this README file
+* open html/all.html
+
+
+See the file LICENSE for details on how this all may be used.
