# Informal Spec:
#
# A User may have multiple Repositories
# A Repositories contains Packages
#
# A User will search for a repository giving a name and optional version
# Each Repository will be scanned for matching Packages
# If only one Package matches, that Package will be opened
# If more than one Package matches, then the user will be prompted to pick one
# While any two Packages share the same name their parent dir is appended
# If no Repository matches, then qwandry will exit with a -404 (repo not found)
