What is Subversion

Subversion® is an open-source version control system. Subversion® allows developers to share there projects on the repositories, where they are stored afterwards. Repository is much similar to a file server, except the fact, that it not only stores the copy of the file system, but its previous states and changing history. Subversion® access its repositories using network, so it provides a probability for a person to work over some shared files and watch for every possible changes made by other developers.

Tags are a kind of specific labels for a set of files each with its own revision number. Used to track the important events if project's life cycle.

Apache Subversion - provides an API for Subversion developers and package maintainers to build Subversion from source code

Binary packages - packages from volunteers built on top of Apache Subversion
- some of the available packages are here: http://subversion.apache.org/packages.html
- Example: Slik SVN

SVNKit

1) Download and unzip
2) create env.bat with:
set MAVEN_HOME=S:\commons\apache-maven-2.0.10
set ANT_HOME=S:\commons\apache-ant-1.7.0
set JAVA_HOME=R:\commons\bea\jrockit_150_15
set path=%JAVA_HOME%\bin\;%MAVEN_HOME%\bin;%ANT_HOME%\bin;%PATH%;S:\commons\scripts;D:\Program Files\Rational\clearcase\ClearCase\bin;s:\commons\firefox
mvn -version
3) use nyacus as your cmd with the env properties by creating mycmd.bat with:
nyacus -r env.bat (means that you are loading the script file env.bat instead of _nya)
4) can start other apps by creating start command like eclipse.bat:
set path=R:\commons\bea\jrockit_150_15\bin\;%PATH%;
cmd /C start R:\commons\eclipse -data R:\bel\workspace\workspace33 -vmargs -Xms40m -Xmx512m -XX:MaxPermSize=256m
5) launch mycmd.bat
6) start other apps by calling filename of .cmd
