Archives and version updates

[Artur Szostak]

>> I have managed to build my own MacPorts archive for some software we are want to try distribute to our Mac users. However, I wonder how one is supposed to deal with version updates to the software. The documentation is clear enough about updating the Portfiles. But how is the archive supposed to be updated? Can an archive have multiple Portfile version and binary packages? Is there documentation about this that I have missed?

>Exactly what do you mean by "archive"? Are you talking about what is created by running "sudo port mpkg ..."? If so, then when the version of the software or any of its dependencies change, just re-run "sudo port mpkg ..." to create a new package.

By archive I mean the locations in:
/opt/local/etc/macports/archive_sites.conf
what I understand to be kind of the MacPorts equivalent to a binary RPM repository.
