Vadim,

neither in inti-cl.lisp nor in dir_vars.txt I find the variables offered in ui-tips.shtml.
So it seems there is an update necessary.

Variables like *maxima-tempdir* and *maxima-userdir* should be available at Maxima level.

In addition to our discussion about postscript plotting one can think about a variable 
$maxima_gsviewdir for the location of  gsview32.exe (ghostview) on Windows, which is 
false by default and could be set if ghostview is installed.
