TODO:
   
     * Security review.
     * There ought to be a way to make it so things like while {1}
       doesn't go ape and make the process run away. I.e., create a limit
       on the maximum execution time.
     * Lots more commands, to make life easier. PHP would be a good place
       to look for examples.
     * Make file uploads work. Once again, PHP has some code which does
       this, but it looks like a mess. It's a pity that Apache doesn't
       have a standard way of getting stuff out of Mime headers, without
       doing most of the parsing yourself.
     * Configurations options: safe mode, ?.
     * Long term: it would be neat to build something that could use any
       one of a variety of languages, like Perl, Python, Guile..whatever.
     * Internationalization
     * Automated test suite: A Tcl script that calls pages and checks
       them for validity?
     * Long term: maybe have a seperate process running somewhere that
       all the different server processes could talk to, similiar to how
       java servlets work (ridruejo@esi.us.es).
     * Fix up the logo I hacked together with The Gimp:->
