# Check that too-new features of Perl are not being used.
#
# This version of the check script supports mapping various directories to
# different version numbers.  This allows a newer version of Perl to be
# required for internal tools than for public code.
#
# The canonical version of this file is maintained in the rra-c-util package,
# which can be found at <https://www.eyrie.org/~eagle/software/rra-c-util/>.
