So, I have a collection of repo's at my company, on the order of forty or
so. It's never "once you do your check out", it's "oh, I need the bleeding
edge of that package, and this other package, and how did so and so solve
this problem again?"

It's also different in that it could conceivably be more than just the root,
it could just be a simple string substitution alias, which means that a URL


Could be ^qfeyn/.

Not using the shell syntax means it's screamingly obvious this is a
subverion construction, increasing the readability of any shell code that
might involve such thing, and limiting where one would go to look for the
list of aliases. Shell variables can be assigned and munged in too many

The same thing that happens anytime you hand svn a broken URL.
