Customizing Maxima. Renaming Maxima functions

Well, it works but I need to rewrite it all in a more useful way.  I was too focused in the beginning on the display of 
piecewise functions and now I realize this is a mistake, I want it to work well with the rest of Maxima.  I hope to 
eventually release a package which will be of sufficient utility that it might be included in a future release.  I think 
pw(f,x) should return either a summation or an "if then else" based on a flag that the user can change to fit their 
preferences.  Some people have said they have a preference.

There is now the display problem.  The summation notation display actually looks nice to me, so you don't have to use a 
matrix.  I don't like the way wxMaxima displays "if then else's".  I was thinking of altering wxmathml.lisp in wxMaxima 
and maybe more code elsewhere in Maxima to improve the appearence of "if then's" for those who like that way.

I am pretty sure I can do it now.

Thanks,

Rich

Thanks,

That should do it.  Now I just have to change my code to use lists as input using the syntax

integrate(e,x,[v]):=block(

...
)$

I will let you know if it works.

try
f([a]):=a;

f(1,2,3);
f(1,2);
