Hello *,

The current version of maxima is 5.16.3; new versions appear quite often. 
It is very tiresome to edit these 2 files after each of them.

The attached files should work for all previous and future versions of 
maxima, at least until TeX generation in maxima will change in some 
incompatible way (then a new texmacs-maxima-x.y.z.lisp will be needed).

The problem with the above files is that Joris says that they don't work 
on his Mac. I tried them on my friend's Mac notebook, and they work fine. 
The difference can be traced to a single 'sed' command which extracts 3 
components of the maxima version from a line which contains them. The 
following line (when executed in /bin/sh ):

echo 'version 5.16.3, lisp sbcl' |\
sed -e 's/^version \([0-9]\+\)\.\([0-9]\+\)\.\([0-9]\+\).*$/\1 \2 \3/'

should produce

5 16 3

according to sed documentation, and it does so on Linux. It does so also 
on my friend's Mac. Joris says that it does not on his Mac.

Please, MacOS users round here, try this line and tell me if it works as 
expected or not. Maybe, we'll be able to find out what causes problems - a 
specific version of MacOS, of sed or whatever. If we'll be able to write 
this single line in a way that works on all systems, permanent troubles 
with TeXmacs not supporting a new version of maxima will come to end.
