# This function downloads and unpacks an archive file, such as a zip
|
|
|
|
# or tar file. This is primarily useful for dynamically generated
|
|
|
|
# archives, such as GitHub's /archive URLs, where the unpacked content
|
|
|
|
# of the zip file doesn't change, but the zip file itself may
|
|
|
|
# (e.g. due to minor changes in the compression algorithm, or changes
|
|
|
|
# in timestamps).
