     So maybe we should all hack on the GLM procedure. The guts of it are
     just least-squares, but translating from the user's syntax to the
     particular covariance matrix and back will be a lot of work.  I can
     handle the least-squares coding and the post-fit computations, but I
     think someone else should write the code to read the syntax, dole out
     the work to the linear model code, and organize the output. I don't
     mind doing it all myself if no one else wants to pitch in, but it will
     take a lot longer that way.

Dividing the work load is certainly a good idea.   But this is where I
start to show my ignorance about advanced statistical methods.

* Can you summarize what the different tasks are that GLM needs to
perform?   Are they really seperate tasks or specialisations of one
general task?  The name GLM leads me to think the latter.

* Can you post some example syntax of the more common ways that you
think people will use GLM?

* Are there any other commands in the spss language that we should think
about at the same time?  eg MANOVA ANOVA ANACOVA UNIANOVA
