# CAVEAT: Some few variable values that are shown here may be
# misleading. For example, make(1)'s := operator leaves references
# to undefined variables as-is, so they may be resolved later. So
# if you want to take a snapshot of the exact value of a variable,
# you have to use "snapshot!=printf %s ''${var:q}" instead of
# "snapshot:=${var}".
