Welcome to the Git crash course for SVN users! This introduces you to Git based on your current Subversion knowledge. If you want to migrate your company from SVN to Git, see the SVN migration page. If you want a list of common commands, see the Git Cheat Sheet (or the git-svn guide if you are using Git as a subversion client. Many non-SVN-specific guides are also available. This crash course is based on Pasky's unmaintained version.

Fossil is a simple, high-reliability, distributed software configuration management system with these advanced features:
-
Integrated Bug Tracking, Wiki, and Technotes - In addition to doing distributed version control like Git and Mercurial, Fossil also supports bug tracking, wiki, and technotes.
-
Built-in Web Interface - Fossil has a built-in and intuitive web interface with a rich assortment of information pages (examples) designed to promote situational awareness.
-
This entire website¹ is just a running instance of Fossil. The pages you see here are all wiki or embedded documentation. When you clone Fossil from one of its self-hosting repositories, you get more than just source code - you get this entire website. (¹except the download page)
-
Self-Contained - Fossil is a single self-contained stand-alone executable. To install, simply download a precompiled binary for Linux, Mac, OpenBSD, or Windows and put it on your $PATH. Easy-to-compile source code is also available.
-
Simple Networking - No custom protocols or TCP ports. Fossil uses ordinary HTTP (or HTTPS or SSH) for network communications, so it works fine from behind restrictive firewalls, including proxies. The protocol is bandwidth efficient to the point that Fossil can be used comfortably over dial-up.
-
CGI/SCGI Enabled - No server is required, but if you want to set one up, Fossil supports four easy server configurations.
-
Autosync - Fossil supports "autosync" mode which helps to keep projects moving forward by reducing the amount of needless forking and merging often associated with distributed projects.
-
Robust & Reliable - Fossil stores content using an enduring file format in an SQLite database so that transactions are atomic even if interrupted by a power loss or system crash. Automatic self-checks verify that all aspects of the repository are consistent prior to each commit.
-
Free and Open-Source - Uses the 2-clause BSD license.
Trac is an enhanced wiki and issue tracking system for software development projects. Trac uses a minimalistic approach to web-based software project management. Our mission is to help developers write great software while staying out of the way. Trac should impose as little as possible on a team's established development process and policies.
