haiku/headers/os/package/PackageResolvableExpression.h
Oliver Tappe 0d68f6afb3 Implemented repository writing:
* fleshed out RepositoryWriterImpl
* renamed BRepositoryHeader to BRepositoryInfo (in accordance with
  BPackageInfo)
* adjusted BRepositoryInfo to be able to parse itself from a
  driver_settings file
* added package_repo binary (only 'create' works as of yet)
