== Using Darcs ==

If you're going to be doing any real hacking on DDC its highly recommended that you use more than one Darcs branch to do it in. Darcs being a Distributed Version Control System (DVCS) means that its designed to make merging between branches easy.

First of all you want a pristine version of ddc-head which you can get using:
{{{
mkdir $HOME/ddc/
cd $HOME/ddc/
darcs get http://code.haskell.org/ddc/ddc-head
}}}

Then for each bug or feature you're working on you probably want a branch which should branch off your local ddc-head branch using:

{{{
cd $HOME/ddc
darcs get ddc-head bug-XXXX
}}}

You can then work on `bug-XXXX` independently from other bugs, while still keeping your `ddc-head` branch up-to-date with regular
{{{
`darcs pull -a`
}}}
commands.

Finally, when you come up with a fix for the bug, you can do a
{{{
darcs push -a
}}}
in your `bug-XXXX` branch which pushes it to your local `ddc-head` branch where you can review it before doing either a
{{{
darcs send
}}}
command to send a patch to the mailing list or a
{{{
darcs push -a
}}}
if you have commit access to the upstream repo.
