They both do; this is something Mark Calabretta had in the original ATNF
AIPS network environment, and we preserved it when backporting those
features to the mainstream AIPS in 1992.  DADEVS.PL was merely written
later as an adjunct to DADEVS.SH to try and speed up the shell scripts
(perl was much faster on a Sparc IPX than bourne shell).
