#
# Summary: Package an installed Python version as a relocatable binary (experimental)
#
# Usage: pyenv binary <command> [<args>]
#
# `pyenv binary` packages an already-installed Python version into a relocatable
# archive that can be installed on another machine. It is experimental and does
# not touch `pyenv install' or any other command.
#
# Run `pyenv binary' to list its commands, or `pyenv binary <command> --help'
# for command-specific help.
