svn_load_dirs.pl does not preserve any more history from the remote
code base than is included in the repository export that you import.
Further, since it is importing exports and is not accessing the
repository directly, you will lose any Subversion properties,
externals definitions, etc.

svn_load_dirs.pl is a Perl script and is in the Subversion source

svn-load is a new script written in Python which is available at
http://free.linux.hp.com/~dannf/svn-load/ . I don't know what its
features are compared with svn_load_dirs.pl.
