# Generic wrapper for makedat.

# Usage: makedat.sh -src=src -file=file -tmp=tmpfile -hup=hupfile [ -cidr ]
#
# Create [file] from [src].  [src] can be either a plain text file, or a
# directory. [tmpfile] is used.  if [hupfile] is specified and it exists,
# this file contains a PID, which is SIGHUPed.
#
# -cidr - [src] contains a list of IP netblocks.  Expand entries in [src]
#         that use CIDR or start-end notation using the Net::CIDR Perl
#         module.  Download the Net::CIDR module from
#         http://www.cpan.org/authors/id/M/MR/MRSAM/
