 ** Compilation
-Colourising the compilation buffer so ANSI colour codes get computed.
+Compilation mode, a super useful subsystem of Emacs which allows one
+to run arbitrary commands.  If those commands produce errors,
+particularly errors that have a filename, column and line,
+compilation-mode can colourise them and automatically help you
+navigate to them.  Very nifty.
+
+Here I add some bindings and a filter which colourises the output of
+compilation mode for ANSI escape sequences; eyecandy is certainly nice
+but it's just useful when dealing with tools that use those codes so
+you can actually read the text.
