maxima user initialisation file - example



dear group,

AFAIK the maxima user initialisation file delivered with the installation routine is
empty.
I would like to know what is typically included in such a file and whether special syntax
is to be used. I have seen some hints in this mailing list, but I would like to see an
working non-empty example of 'user initialisation file'.

It would be very kind if someone would send me such an file, so that I could study its
contents to learn from it. I'm using Maxima 5.12/wxMaxima 0.72 with WindowXP.
