One Quickie
Adding new project to repository (1 project : 1 repository) (Subversion->General)
The Subversion folks recommend that project have a branches, tag, and trunk directory, to make doing things like branches and tags easier. Importing this way will mean your repository will only have this one project.
% mkdir DungeonBorkventure
% cd DungeonBorkventure
% mkdir branches tags trunk
# put source files into trunk
% svn import . file:///usr/local/svnroot -m "initial checkin"
% cd ..
% rm -rf DungeonBorkventure # or move it aside
% svn checkout file:///usr/local/svnroot/trunk DungeonBorkventure
% cd DungeonBorkventure
# and get to work
