# This program dispatches among
#   - the shell implementation and
#   - the Python implementation
# of gnulib-tool, according to the environment variable GNULIB_TOOL_IMPL.

# The environment variable GNULIB_TOOL_IMPL can have four possible values:
#   - GNULIB_TOOL_IMPL=sh      chooses the shell implementation.
#   - GNULIB_TOOL_IMPL=py      chooses the Python implementation.
#   - GNULIB_TOOL_IMPL=        chooses the default (the Python implementation
#                              if a suitable Python version is found, the shell
#                              implementation otherwise).
#   - GNULIB_TOOL_IMPL=sh+py   runs both implementations and compares the
#                              results.
