package_repo requires a url in repo-info file which needs eval

[kallisti5]

package_repo requires a url in the repo-file.

This really doesn't make sense. You're always going to know the repo's base url... so why would you need to specify it while building the repo?

This makes repo creation a lot more complex than it needs to be... I also haven't been able to find anywhere the repo.info url is actually used. (don't get a packages's URL mixed up the internal repo url)

Example:

URL: ​http://packages.haiku-os.org/haikuports/master/repo/x86_64/c623cf2b4d85bc452d5a21a2586e552fe1b04f6d66eca0663f257461c106db9f/repo.info

name HaikuPorts
vendor "Haiku Project"
summary "The HaikuPorts repository (for Haiku hrev50482)"
priority 1
url http://packages.haiku-os.org/haikuports/master/repo/x86_64/c623cf2b4d85bc452d5a21a2586e552fe1b04f6d66eca0663f257461c106db9f
