Getting the source code
From AbiWiki
If you are just starting out with AbiWord you will need to get the latest development version of the source code with this command.
svn co http://svn.abisource.com/abiword/trunk abiword
Once you have a commit access to AbiWord you use subversion to get the main tree and plugins with this command (where "<username>" is you svn access name):
svn co svn+ssh://<username>@svn.abisource.com/svnroot/abiword/trunk abiword
If you need to get the 2.8 branch do:
svn co svn+ssh://<username>@svn.abisource.com/svnroot/abiword/branches/ABI-2-8-0-STABLE/ abiword-2.8
If you need to get the 2.6 branch do:
svn co svn+ssh://<username>@svn.abisource.com/svnroot/abiword/branches/ABI-2-6-0-STABLE/ abiword-2.6 svn co svn+ssh://<username>@svn.abisource.com/svnroot/abiword-plugins/branches/ABI-2-6-0-STABLE/ abiword-plugins-2.6
After the 2.6 branch the plugins have been integrated into the main build system.
