Create README.md

This is essentially a copypaste from the Gcode project, although I've made a couple changes and will probably make more.

+Classic Blades of Exile
+=======================
+
+This project hosts the source code to the classic RPG creator Blades of Exile after it was released
+by Spiderweb Software under GPLv2. It is a svn-git transfer from the
+[Google Code Progect](http://code.google.com/p/openexile/); all issues and trunk code has been ported.
+
+The primary purpose of this project is to provide bug fixes to Blades of Exile
+so that it can compile and run on modern operating systems. The secondary purpose is
+to generalize and extend its functionality while maintaining backwards compatibility.
+
+If you would like to be added to this project contact [Sylae](https://github.com/sylae)
+or one of the other people on the owners list. This is an open project, with no strong prerequisites
+for getting commit access. With that in mind, please be careful of what you check into the repository.
+Please do not commit any binaries, junk files, or anything that doesn't compile.
+
+The current task at hand is to merge the Mac and Windows code into the unified wxWidgets code base.
+
+Linux
+-----
+
+At last, there is a potential Linux version available in the downloads (though so far only the
+Character Editor is available). This should be treated as an alpha/beta release, so use with caution.
