Architecture
•
Access URLs
file://hostname/path/to/repos
On local machines the hostname part must either be absent or localhost.
•
This results in a path like this one:
file:///path/to/repos
•
On Windows you have to specify the drive where to find the repository:
file:///X:/path/to/repos

Repository Layout
trunk/tags/branches on root;
each module will be tagged separately
•checkout of all modules is possible
•commits can span multiple modules
•tags can not span multiple modules in single commit
(workaround by 3rd party tools)
