Monotone is used by very few projects these days. It had a pioneering design, but several implementation and interface problems that made it not very suitable for doing real work (the fact that Git is easier to use than Monotone, at least the last time I tried it, says a lot).

Here is the currently listed set of steps for checking out the Monotone source code:

$ mtn --db=mtn.db db init
$ mtn --db=mtn.db pull monotone.ca "net.venge.monotone*"
$ mtn --db=mtn.db checkout -r t:monotone-0.28 monotone

Compared to the steps for Git, Hg, and Bzr:

$ git clone git://git.kernel.org/pub/scm/git/git.git
$ hg clone http://selenic.com/hg mercurial-repo
$ bzr branch http://bazaar-vcs.org/bzr/bzr.dev bzr.dev

Add on the fact that the data format changes on each release and thus requires a migration, that it's fairly slow, and it just isn't really competitive with the other options these days.

Well, if you do it with git's plumbing, it is similarly hard:

$ git init $ git remote add origin git://git.kernel.org/pub/scm/git/git $ git fetch remote $ git reset --hard origin/HEAD $ git config branch.master.remote origin $ git config branch.master.merge master

It looks that mtn is still much of the plumbing tool that git once was, so at least give it some slack when doing comparisons :-)

Unless monotone offers a simple command to do the equivalent of the three commands given, the criticism stands. It is also possible to expand the "bzr branch" command into multiple steps, but people would very rarely do that.

it does ...

mtn clone monotone.ca net.venge.monotone

Yes, but Monotone has been around for several years longer than Git. Git was in fact inspired by the
design of Monotone, but implemented to be much more efficient and to work better as a plumbing
system that you could wrap porcelain around. Monotone is a big monolithic blob of C++, so it's
fairly difficult to link to, and only around the time that Git was being developed did Monotone start
addding a scripting interface with a standardized, parseable output format. And even still, there
doesn't appear to be very good porcelain around it, while Git's design has meant that more
porcelain has been written more quickly.
