svnadmin create — Create a new, empty repository.
Create a new, empty repository at the path provided.
If the provided directory does not exist, it will be
created for you. As of
Subversion 1.2, svnadmin creates new
repositories with the
backend by default.
Creating a new repository is just this easy:
$ svnadmin create /usr/local/svn/repos
In Subversion 1.0, a Berkeley DB repository is always
created. In Subversion 1.1, a Berkeley DB repository is
the default repository type, but an FSFS repository can be
created using the
$ svnadmin create /usr/local/svn/repos --fs-type fsfs
 Remember, svnadmin works only with local paths, not URLs.
