SCM tools make developers’ life easier while they are working simultaneously; they help to avoid overwriting changes made by others and maintain the history of every change. SCM tools must manage changes in space efficient way. Large organizations can easily afford to use or adopt one or more commercially available version management tools. Amiga developer Obarthel released a native port of subversion and only needs GCC and the clib2 runtime library. The release is compatible with AmigaOS 3.x and AmigaOS 4.0. The Amiga port is specially adapted to the needs of the Amiga and will retain file system metadata (protection bits, group/owner information and comment text).
