Below there is email I want to send to Shlomi Fish to have him include GIT in "Better SCM Initiative : Comparison page". Please check it and send comments and corrections. TIA. -- >8 -- I have noticed that your SCM comparison at "Better SCM Initiative" website http://better-scm.berlios.de/comparison/comparison.html misses GIT, version control system which is used to manage Linux kernel. GIT was created by Linus Torvalds in response to the change of BitKeeper licensing, as a tool to manage Linux kernel sources. It is based on three years of Linus experience with BitKeeper, and inspired by Monotone architecture. It was designed for Linux kernel, and is used by various projects, including X.Org, various Freedesktop projects, WINE, OLPC (One Laptop Per Child), Samba. <blurb src="http://git-scm.org";> Git is a popular version control system designed to handle very large projects with speed and efficiency; it is used mainly for various open source projects, most notably the Linux kernel. Git falls in the category of distributed source code management tools, similar to e.g. GNU Arch or Monotone (or BitKeeper in the proprietary world). Every Git working directory is a full-fledged repository with full revision tracking capabilities, not dependent on network access or a central server. Git is an Open Source project covered by the GNU General Public License v2. It was originally written by Linus Torvalds and is currently maintained by Junio C Hamano. </blurb> Below there is patch to the sources for the site. BTW. when asking about updating GIT info for comparison, please CC git mailing list, git@xxxxxxxxxxxxxxx Index: src/comparison/scm-comparison.xml =================================================================== --- src/comparison/scm-comparison.xml (revision 290) +++ src/comparison/scm-comparison.xml (working copy) @@ -38,6 +38,9 @@ <implementations> <impl id="darcs"> <name>Darcs</name> </impl> + <impl id="git"> + <name>Git</name> + </impl> <impl id="mercurial"> <name>Mercurial</name> </impl> @@ -106,6 +109,7 @@ <title>Atomic Commits</title> <s id="svk">Commits are atomic.</s> <s id="aegis">Commits are atomic.</s> <s id="bitkeeper">Yes (but need to verify)</s> + <s id="git">Yes.</s> <s id="mercurial">Yes.</s> <s id="monotone">Yes.</s> <s id="opencm">Yes.
