Obviously, this should be documented.

So that you don't have to rediscover this again, you can self-document
'simp' using my 'user_doc' function available at

http://www.maths.ed.ac.uk/~lbutler/maxima-packages.html

I would download it to my .maxima directory, unpack it, and add
'load("<path-to-dot-maxima-dir>/cl-info.lisp");' to maxima-init.mac
to have it autoloaded.


Here's a sample:

(%i201) user_doc("simp");
Enter documentation string surrounded by quotes '"'.
End input with ';'.
" -- Global variable: simp
     default value: true

  Boolean that controls Maxima's simplifier; if true,
  then simplifier is applied to input; if false, it is
  is not.

(%i2) simp : false$
(%i3) sin(1.0);
(%o3) sin(1.0)
(%i4) simp : true$
(%i5) sin(1.0);
(%o5) 0.8414709848079
";
(%o201) "simp"
(%i202) ? simp

 -- Global variable: simp
     default value: true

  Boolean that controls Maxima's simplifier; if true,
  then simplifier is applied to input; if false, it is
  is not.

(%i2) simp : false$
(%i3) sin(1.0);
(%o3) sin(1.0)
(%i4) simp : true$
(%i5) sin(1.0);
(%o5) 0.8414709848079

  There are also some inexact matches for `simp'.
  Try `?? simp' to see them.

(%o202) true
(%i203) ?? simp
