For the -0.0.1 alpha version we have one html document
that is a meager attempt at describing what abbruch is
capable of at this point.

Since this may be considered to be a little cryptic, it
would be nice to have an easier to read version of this
document.

Perhaps we should address the fact that pop mail only
(i.e. ones without a shell login) cannot use this tool
(yet)
