# override the versioned entry points in the wheel and generate the

# To add the level of hack in this section of code, in order to support
# ensurepip this code will look for an ``ENSUREPIP_OPTIONS`` environment
# variable which will control which version scripts get installed.
#
# ENSUREPIP_OPTIONS=altinstall
# - Only pipX.Y and easy_install-X.Y will be generated and installed
# ENSUREPIP_OPTIONS=install
# - pipX.Y, pipX, easy_install-X.Y will be generated and installed. Note
# that this option is technically if ENSUREPIP_OPTIONS is set and is
# not altinstall
# DEFAULT
# - The default behavior is to install pip, pipX, pipX.Y, easy_install
# and easy_install-X.Y.
