# used to filter out non-matching packages. Example: 'Dan'.
#
# In addition to server and file availability checks, expected
# and actual (computed) checksums are compared. Files which are
# already present in the cache directory are skipped.
#
# Currently, up to approximately 9 GB of data may be downloaded.
