376 compatible install in a way that is very close to the on-disk format.  Many
packages will be properly installed with only the @code{Unpack} step and the
unpacked archive preserves enough information to @code{Spread} (copy data and
scripts to their final locations) at any later time.  Wheel files can be
installed with a newer @code{pip} or with wheel's own command line utility.")
