SVN (subversion) makes cooperative development easy.
First, you need subversion client installed in your system. In case of fedora/redhat, install it using yum:
yum install subversion
Create directory for openrrcp source, go there, issue “svn checkout”. Something like this:
mkdir /usr/local/src/openrrcp cd /usr/local/src/openrrcp svn checkout http://openrrcp.svn.sourceforge.net/svnroot/openrrcp/trunk/ cd trunk make
If you have found a bug and fixed it, just issue “svn diff” and submit output to maintainer nording@yandex.ru or create ticket here
