Current public branches:

• http://www.greenend.org.uk/rjk/bzr/disorder.dev is the main development branch
• http://www.greenend.org.uk/rjk/bzr/disorder.4.3 is the 4.3 fixes branch
• http://www.greenend.org.uk/rjk/bzr/disorder.4.3-rel is the 4.3 release branch

If you visit a branch's URL in a web browser you can see the code (at the branch tip). Currently there is no public history browser, though I hope to make a public Loggerhead available sometime.

You can check out the development branch with bzr, for example:

$ bzr clone http://www.greenend.org.uk/rjk/bzr/disorder.dev
$ cd disorder.dev
$ bash ./prepare
[some output]
$ ./configure -C
[lots of output]
$ make                    # gmake on FreeBSD
[lots of output]

You should read README.developers.
