Mercurial
I just started working with Mercurial, a new distributed SCM system and I have to say that I am quite impressed. Mercurial is a direct competitor to GNU Arch, Darcs, BitKeeper, Monotone, and other open-source distributed SCMs, however it seems very well architected and polished.
I was particularly impressed by the fact that you not only run it as a command-line utility, but you can run the same program a web server, allowing you to distribute your files over a network; You can also configure it to run as a .cgi script, so that if you have a larger web site, you can incorporate a Mercurial repository within it fairly easily.
The code was pretty easy to set up and use. Within less than an hour, I was able to:
- Compile and install the package on my laptop.
- Create an initial repository.
- Check in an example file.
- Compile and install Mercurial on the remote host I use for viridia.org.
- Propagate the changes from my laptop to the server.
- set up Mercurial to function as a .cgi script.
- write a .htaccess file to tell Apache to use it.
You can see the result here.
