# This is very simple POSIX sh script which
# identifies the first matching
# python3 identifier in $PATH and produces
# configure.py from configure.py.in, and then
# calls the new executable configure.py.
#
# It should be portable on Unices. Report bugs on
# the bugtracker if you discover that it isn't
# working as intended.
