I am looking to make a base build of source code and store it in Subversion, I then want to create a number of builds based on the source with key files shared/mirrored in all the subsequent builds so I can apply global updates to the shared/mirrored files of the builds and run an update so I only have to make the change once.
I know this is possible in Micorsoft VSS, does a feature like this exist in Subversion with TortoiseSVN on Windows using VisualSVN?
