svn export — Export a clean directory tree.
The first form exports a clean directory tree from the
repository specified by URL, at revision
REV if it is given, otherwise
at HEAD, into
PATH. If
PATH is omitted, the last
component of the URL is used
for the local directory name.
The second form exports a clean directory tree from
the working copy specified by
PATH1 into
PATH2. All local changes will
be preserved, but files not under version control will not
be copied.
