python2-wheel 0.36.2 Format for built Python packages
A wheel is a ZIP-format archive with a specially formatted filename and the
.whl extension. It is designed to contain all the files for a PEP 376 compatible install in a way that is very close to the on-disk format. Many packages will be properly installed with only the
Unpack step and the unpacked archive preserves enough information to
Spread (copy data and scripts to their final locations) at any later time. Wheel files can be installed with a newer
pip or with wheel's own command line utility.
