Each project in the svn should be arranged like this:
"documentation" holds all documentation related to the project. Such as manuals, license files etc.
"src" holds all source files needed to build the project, including make files. Sub folders may contain needed binaries such as images.
"release" holds the latest release binary with related files such as file icons and update history.
"contributors.txt" contains a list of users that has contributed to the project.
