That's really good of Bill.

Several technologies come to my mind, that could give a multi-platform
version.

1) WxWidgits in C++

2) Qt in C++

3) Mathplotlib in Python.

4) GNUplot

5) Command line version for UNIX and UNIX-like systems.

I would not be surprised if Poul-Henning Kamp would be interested in
porting to FreeBSD too.

Solaris is pretty much dying since Oracle bought Sun, so there are
arguments for not bothering with a Solaris port. But from my experience,
testing software on multiple platforms often highlights bugs that exist in
all platforms, but have not been discovered. I lost count of the number of
hours I spent porting Sagemath to Solaris, but a number of bugs were
discovered by me whilst porting to the Solaris. Those bugs existed on
Linux, but had just not manifested themselves.

I assume, but perhaps are mistaken, you mean Linux here. Strictly speaking,
a system is not UNIX unless certified by The Open Group. Linux is certainty
not UNIX, and in several cases the code breaks UNIX compatibility. For
example, on Linux, the df command reports sizes in kb, but for UNIX system
it is 512 byte blocks. I don't know, but I suspect FreeBSD conforms to the
UNIX standard more than Linux. Also on Linux, people tend to use tools like
'which'

drkirkby at hawk:~$ which ls
/usr/bin/ls

to find the path to an executable. But 'which' is not part of the UNIX
standard, so may not be available on a UNIX system.  But the following
gives the same information

drkirkby at hawk:~$ command -v ls
/usr/bin/ls

but works on UNIX systems in addition to Linux systems.
