The first thing you should do is make sure you have the cvs package installed. Second, if you have a directory or file named rpm in your home directory, either delete it or move it somewhere else. You don't want it to get in your way in the next step. Now, invoke the following set of commands:

$ cd

To make sure your current working directory is your home directory.

$ mkdir -p rpm/{RPMS,BUILD,SRPMS}

To create necessary directories.

$ CVSROOT=:pserver:cvs@cvs.pld-linux.org:/cvsroot \
cvs co SOURCES/.cvsignore SPECS

NB! Alternative initialization

$ poldek -u rpm-build-tools
$ builder --init-rpm-dir

Read more aboout builder script.

To fetch all the files from the repository. If you already have an account there, replace cvs@cvs.pld-linux.org with your account name.

Now you are ready to start your work.
