Very much a "work in progress"
Uses Guile Scheme and Cairo to make plots and do some basic numerical methods
Requires::
guile
cairo
guile-cairo
N.B. - Installing guile-cairo from the Debian/Ubuntu repos is out of date with the cairo package and leads to a seg fault. guile-cairo must be installed from source.
The guile and cairo packages for Debian/Ubuntu are sufficient.
I am unable to make the brew formula for cairo work on MacOSx
Possibly use GTK to embed Scheme REPL and Cairo canvas in a simple GUI program.
