I just implemented a "--userdir" argument to Maxima and committed it to 
cvs. I have attached an example of usage at the end of this message. If 
the change is satisfactory, I will update the man page. The dos maxima 
script also needs to be updated.

Earlier in this thread I said I thought there was a bug in the 
implementation of MAXIMA_USERDIR. Upon further reflection, I can't find 
anything wrong with MAXIMA_USERDIR. It works as advertised.

I think rmaxima should put its history file in MAXIMA_USERDIR. I'll fix 
that soon.

/* load("colorterm.lisp");colorterm(); */
print("jfa in default directory");
