   7 # Generic wrapper for makedat.
   8 #
   9 # Usage: makedat.sh -src=src -file=file -tmp=tmpfile -hup=hupfile [ -cidr ]
  10 #
  11 # Create [file] from [src].  [src] can be either a plain text file, or a
  12 # directory. [tmpfile] is used.  if [hupfile] is specified and it exists,
  13 # this file contains a PID, which is SIGHUPed.
  14 #
  15 # -cidr - [src] contains a list of IP netblocks.  Expand entries in [src]
  16 #         that use CIDR or start-end notation using the Net::CIDR Perl
  17 #         module.  Download the Net::CIDR module from
  18 #         http://www.cpan.org/authors/id/M/MR/MRSAM/
