Just what would be needed in the minimal extensible editor? (Not the
mathematical minimum since that is a turring machine) Certainly the folowing
is needed:

1) The ability to define/redefine commands. Which means some sort of
   extension language including:
   1.1) WHILE .. DO ..
   1.2) IF .. THEN .. ELSE .. (The ELSE is of course optional)
   1.3) Variables: Local, and Global (This implies include simple math
        functions, assignment, and comparison)
   1.4) The ability to call other commands and editor primitives.
   1.5)	Input Output commands.
   1.5) An interactive debugger? (it would be painfull to use this language
        to develope a ~REAL~ editor without it)
   1.6) Other looping constructs? Perhaps a case type statement.

2) Some means to connect commands to keys, and some way to disconnect them.

3) Due to the size limitations of most machines, a way to load libraies of
   functions and to "Unload" them (ie. get them out of core).

4) Editing primitives. Including:
   4.1) Movement - both relative and abolute.
   4.2) Insertion
   4.3) Delteion
   4.4) Searching
   4.5) Multiple buffers
	4.5.1) Creation of
	4.5.2) Deletion of
	4.5.3) Selection of

5) Display package? Should this be at a low level and thus fast, or should
   it be written in the extension language and thus easily modified?

I would appreciate comments-suggestions-extensions to the above.
