Not much, just yet.
Current source is prealpha, as some basic editor functions are still missing.
When it reaches notepad level of editor functions (things like cut and past are still missing) I will consider it beta.
and may give this page a face-lift and make some file packages.
Till then you may get the source using:
cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/cppedit login
cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/cppedit co cppedit
