Recently I imported a subversion repo for one of my projects into git. However, I had a non-standard directory setup since I did not follow the common /path/to/repo/project/{trunk,tags,branches} directory layout convention. Instead, I had originally setup /path/to/repo. I needed a way to specify that I didn't have a trunk directory.

Here's what I did to import that into a git repo:

git svn clone -t '' -b '' -T '' svn+ssh://host.tld/path/to/repo/

Upon running this command, I did see errors stating that I hadn't specified branches or tags properly, so it's possible that those flags are superfluous in my case, but in any event the -T '' was essential to a successful import.

In the process of finding the magic flag for importing, I found http://jo.irisson.free.fr/?p=64 to be particularly descriptive and helpful in my understanding of the import process. However, git-svnimport has been deprecated, so I used git-svn instead.
