 Hi Jeronimo and Robert,

I grepped the sources and (I think that I) found 153 Maxima functions
that are defined using defmspec... it would be good to have a nice way
to jump to their sources, but I confess that I would be happy with a
non-nice way, too. I just found that if I run this,

  to_lisp()$
    (describe '$changevar)
    (describe '$tex)
    (symbol-plist '$tex)
    (get '$tex 'mfexpr*)
    (to-maxima)

the output of the "(get '$tex 'mfexpr*)" is:

  #<FUNCTION (LAMBDA (L) :IN "/home/edrx/bigsrc/maxima/src/mactex.lisp")
{52FB567B}>

how do I extract the "/home/edrx/bigsrc/maxima/src/mactex.lisp" from
that?

  Thanks in advance =P,
