This is the top of the Subversion repository.
trunk/ ......... The latest development sources. When people say
"Get the head of trunk", they mean the latest
revision of this directory tree.
branches/ ...... Various development branches. Typically a branch
contains a complete copy of trunk/, even if the
changes are isolated to one subdirectory. Note
that branch copies are generally removed after
they've been merged back into trunk, so what's in
branches/ now does not reflect all the branches
that have ever been created.
tags/ .......... Snapshots of releases. As a general policy, we
don't change these after they're created; if
something needs to change, we move it to
branches and work on it there.
emptydir/ ...... using for svn switch target to omit large
directories which not needed.
README/ ........ This file.
