La rez

hi allan,

we finally got around pushing our local changes (in LA) back to a branch on github !
there is more in it than one would want to merge, in particular the custom configuration scripts, but i am new to this process and would be happy and go back to clean up the request if you need me to. please just let me know.
there are some fixes in this branch, some new features or options but the main update, that justified the 1.7 upgrade, is the extension of versions to support something mentioned on the 'future work' section as:

"● change versioning to support arbitrary representations that can be registered with the system, eg
to support conventions like 1.2a, 4.5.b0, 6.rc1.4."

there is also the ability to use @ as a separator between package name and version.

also, blacklisting and archiving is now fully supported.

anyway, please review and let us know how we should proceed from here on.

thanks always !
