shell variable scenario: gcc.gnu.org has a special file that people can 
check out to get settings
for the several hundred tags & branches, which they have to massage with 
a sed script to
generate a file that is sources by .profile / .bash_profile to agree 
with the access methods
required to get throuh the local firewall, so something that looks like:
export 
gcc_4_1_1_release='svn+ssh://amylaar@gcc.gnu.org/svn/gcc/tags/gcc_4_1_1_release'

now that I have expanded my environment by hundreds of variables, I can do:
svn diff Makefile.in  $gcc_4_1_1_release/gcc/Makefile.in

But I'd rather do:
svn diff Makefile.in -rgcc_4_1_1_release

I.e. no silly naming of the path from the trunk root to the file, and no 
repetition of the file name itself.
