-When using the options for describing the repository layout (--trunk,
---tags, --branches, --stdlayout), please also specify the --prefix
-option (e.g. '--prefix=origin/') to cause your SVN-tracking refs to be
-placed at refs/remotes/origin/* rather than the default refs/remotes/*.
-The former is more compatible with the layout of Git's "regular"

 When using multiple --branches or --tags, 'git svn' does not automatically
 handle name collisions (for example, if two branches from different paths have
 the same name, or if a branch and a tag have the same name).  In these cases,
