< And most of the newly expanded options aren't defined. I guess that

Getopt_long has been ported to cl by K Rosenberg.
There are a few advantages to plugging this into maxima.
If I understand the code correctly, getopt_long knows the options (and
the possible values) which makes for better error-catching and handling.
Alternatively, why not make -o greedy? That is, everything that occurs
after -o is passed to the lisp.
< Also, there seems to be a limitation on the number of command line
< args that can be handled. In maxima, we gather up args 1-9 and pass
< them to the underlying lisp. But what if there were more?
I think this is a bug in the shell script. It looks like the author is
trying to avoid arrays in bash, but I have no idea why.
