Rellor is a reimplementation of Inform 6, the interactive fiction language
that is also used as an intermediate compilation step in Inform 7.
Differences from the original Inform 6 will likely include a relaxation of
memory limits, additional target platforms, code optimization, and possibly
extended syntax.

To build Rellor, you'll need to download antlr-dotnet-csharpbootstrap from
http://www.antlr.org/wiki/display/ANTLR3/Antlr3CSharpReleases and extract it
to the Reference/Antlr directory.
