Re: raster movies

[Paul E. Johnson]

This was documented for swarm 1.3 and was fixed in swarm 1.3.1 as I
recall. Give it a try.

Also,If you use the fli making routine that Marcus posted a while back
and Sven wrote a careful description in the email list, be aware that
Redhat's versions of pngtopnm and some of the other utilities that get
used in the script for making movies are no good. I've got executables
available to replace them at 
http://lark.cc.ukans.edu/~pauljohn/Swarm/ 
in a file with a name like "pngtopnm-2.37compiled" or such. You should
be able to unzip these and put them in place of your ones that don't
work.

 I think there are one or two other binaries that don't work. They are
ones made available by SUSE and are for libc5 systems (not your Redhat).
If you get to that point of making the fli, please tell me when you get
the seg faults and I can give you replacement binaries (but right now I
can't remember which ones they were).
