[darcs-users] [Haskell-cafe] Re: poll: how can we help you contribute to darcs?

[Anatoly Yakovenko]

I would gladly contribute to darcs if I could use it.  And I would use
it if it was fast (at worst twice as slow as git) and stable for the
simple things that i want to do.  So this is a chicken and egg problem
for me.

Maybe if you can gut darcs into a really simple and basic vcs that is
fast and really really stable, and allow plugins that wont compromise
your repository then I would gladly use it and contribute in areas
where i can improve it.
