To get an initial working copy you must check out some
subtree of the repository.
To get a working copy of the calc project:
$ svn checkout http://svn.example.com/repos/calc
A calc
A calc/Makefile
A calc/integer.c
A calc/button.c
$ ls -A calc
Makefile integer.c button.c .svn/
There are several ways of accessing a repository, the two you
might use are:
file:/// (direct access on a local disk)
svn+ssh:// (using custom protocol of svnserve via
an SSH tunnel)
Once you checkout a project, subsequent accesses do not need
the full specifier, the information needed is in the local working
copy.
