Well there already is a backend library and a console client codenamed
maelstrom. Currently it has limited functionality. It can work with
packages locally(update, freshen, remove) and currently I'm developing
the sync components for it - a finished a ftp backend library, I have to
create one for http communication as well. It understands the
pacman.conf format and in the final version I guess I'll reuse
pacman.conf itself. I hope I'd be able to show the community a working
beta by the end of the month. Some of the advanced functionality won't
be implemented by then of course but I'll do my best to rival pacman's
features and even provide a couple new... Maelstrom is of course open
source and is being developed together with a companion project -
Whirlwind, that will try to bring the synaptic functionality to arch's
community wrapped in a pretty GTK# UI.
P.S. Maelstrom started as a set of C# bindings for libapml, but soon I
decided that it would be easier for me to reimplement everything rather
than try to wrap it. The current codebase also seemed to me cluttered
and inconsistent so I took the "from scratch" approach...
