The banner from my version of Spice says this:

AmigaSpice 5.0     (Spice 2G.6)


This Program is Public Domain

 Usage:
 SPICE i/o_file

                     Input file assumed to be: i/o_file.INP
                          Output file will be: i/o_file.OUT


The program IS written in 'C' (so the conversion has been done) and for
those of you who don't already know it, auto detection and support of
a math co-processor, was include in 1.3, as is evidenced by the VAST speed
increase of this version of SPICE on my 2630 (6x faster). A second version
with inline 881/882 code would be nice because we might then get to the
8x or even 10x faster mark. Also, as I have said before, there is a
program to plot SPICE files called SPlot, available via ftp at
sunne.waterloo.cs (I think). It should soon include ARexx support for
full automation, at which point I would expect it to be posted to
c.binaries.amiga. This program also supports extra functionality not
found in SPICE like plotter output, arbitray zoom etc.
