The software changes are tracked with subversion on the Sourceforge site.
The subversion repository allows anonymous access. Use the following command to checkout the latest version of the code:
svn checkout svn://svn.code.sf.net/p/frepple/code/trunk frepple-code
The repository content can also be browsed online at http://sourceforge.net/p/frepple/code/ Detailed checkout instructions are also available on this page.
A example subversion configuration is available in the file subversion.config for convenience. In particular the section on the automatic properties is of interest when adding files to the project.
