.Ss ISO9660 format
Libarchive can read and extract from files containing ISO9660-compliant
CDROM images. It also has partial support for Rockridge extensions.
In many cases, this can remove the need to burn a physical CDROM.
It also avoids security and complexity issues that come with
virtual mounts and loopback devices.
.Ss Zip format
Libarchive can extract from most zip format archives.
It currently only supports uncompressed entries and entries
compressed with the
.Dq deflate
algorithm.
Older zip compression algorithms are not supported.
