# Some downloads are available via HTTPS only, but wget < 3.14 does not support
# server-name identification, which is used by some sites. So, we disable
# certificate checking in wget and check the validity of the download via SIG
# or SHA.
#
# Successful and integrity-checked downloads are cached at the
# GENODE_CONTRIB_CACHE directory. The combination of 'cp' and 'mv' when
# populating the cache prevents corrupted files in the cache when the disk is
# full.
