# this perl script is designed for the ifmail package by eugene grosser.
#
# request a file (first argument) from a fido-node (second argument),
# don't forget to quote if you use wildcards, e.g.:
#
#      ifreq 'files*' 2:2410/305
# or
#      ifreq 'files newfile' 2:2410/305
#
# this perl script does only add an entry to the corresponding flo-file,
# the mailer ifcico is not started!
