There are lot of functions and more of them will be added. I think it is
cumbersome to update wiki or ask users to go to wiki to find out
documentation. instead each user defined function can have an annotation
containing documentation and 'show functions' command or similar can show the
documentation to users on command line. it will also be easier to update the
documentation along with code.
