How to install

$ sudo apt-get install make locales autoconf libreadline-dev \
  libwww-perl libconfig-yaml-perl graphviz haskell-platform drift pandoc \
  libghc-readline-dev libghc-utf8-string-dev libghc-hssyck-dev libghc-pandoc-dev

$ autoreconf -i
$ ./configure
$ make
$ sudo make install

For developing

Please use the arafura branch, rather than master branch.

master branch: Do not touch me, mirror of jhc's darcs repository.
arafura branch: For developing Ajhc.

You should send patch to jhc, if testing on Ajhc is good.

$ darcs get http://repetae.net/repos/jhc
$ cd jhc/
$ patch -p1 < ~/yourfile.patch
$ darcs record -a
$ darcs send

The command darcs send sends email the patch to jhc author (= John Meacham).
