# Match the age of a file, for use as a glob qualifer.  Can
# take one or two arguments, which can be supplied by one of two
# ways (always the same for both arguments):
#
#   print *(e:age 2006/10/04 2006/10/09:)
#
# Match all files modified between the start of those dates.
#
#   print *(e:age 2006/10/04:)
#
# Match all files modified on that date.  If the second argument is
# omitted it is taken to be exactly 24 hours after the first argument
# (even if the first argument contains a time).
#
#   print *(e-age 2006/10/04:10:15 2006/10/04:10:45-)
#
# Supply times.  All the time and formats handled by calendar_scandate
# are allowed, but whitespace must be quoted to ensure age receives
# the correct arguments.
#
#   AGEREF1=2006/10/04:10:15
#   AGEREF2=2006/10/04:10:45
#   print *(+age)
#
# The same example using the other form of argument passing.  The
# dates stay in effect until unset, but will be overridden if
# any argument is passed in the first format.
