- Added the comment module to the theories.pdf ("make latex").

- Added a hack allowing to override a theory display with another theory's
display. This is necessary for bootstrapping reasons - it allows one
to get a reasonable output of a theory (e.g. Comment) that is defined before
all essential display forms (e.g. the Summary ones) are there.

- Added debugging code to make it easier to find dforms that cause
zone begin/end mismatch (and used it to get rid of all
the "Unballanced buffer" warnings in "make latex").

- Minor dforms&comments updates.

I've removed old Itt_int* theories and switched all the ITT to Yegor's
new theories.

- Rewrote the Itt_esquash theory based on my "better_tt" ideas.
- Now esquash is a primitive operator and not a defined one.
- This change also broke a few FOL and CZF theories that relied
on a bunch of invalid rules that I had to remove from Itt_esquash.

- Now substitution (s1=s2 in S) for conclution (t in T[s1]) produces a wf subgoal
   s:S |- T[s] Type
(instead of s:S |- (t in T[s]) Type which was annoying)

- Now assertEqT is more powerful than it was.

- added rules applyEquality to intro resource

- many rules (e.g. letT and elimination rules for the intersection and union types)
  produces equality hypotheses in the subgoals that rarely used in practice.
  Now such rules thin these hypotheses by default.
  To avoid this one can use doNotThinT = thinningT false.

Finally fixed the tutorial so that we have a derivation of
classical first-order logic.  The HTML docs are not yet up-to-date.

Things seem to be working pretty smoothly now.  This is mostly minor
fixes.  Still need to fix the problems with the mp toploop.

    1. Proofs now use Alexey's ASCII format.  By default, proofs
       should be saved to CVS in .prla format.  You can generate ASCII
       files by using "make export", or you can use the "export ()"
       instead of the "save ()" command in the editor.  For speed,
       .prlb files are now saved in a raw, marshaled format.  When you
       edit a theory, the newest of .cmoz, .prlb, or .prla files is
       loaded.  There is a new command "convert" to convert between
       all the different proof file formats.
          convert -I ... [-raw|-term|-lib|-ascii] -impl file.cmoz
          raw: save the file in fast, raw format
	  term: save the file as <magic#>/<marshaled term_io>
	  lib: send the file to the Nuprl5 library
	  ascii: create a .prla file

       Developers: _please_ mention any changes to the basic data
          structures in your CVS logs.  The things that matter are:

       Users: to be safe, save all your proofs using "make export"
          before doing a cvs update.

    2. "expand ()" and "expand_all ()" now work.  I also added
       "clean ()" and "clean_all ()" commands to remove those peasky
       dangling proof nodes when you are satisfied with a proof.  By
       default, proofs are saved only down to the innermost rule-box
       level, and primitive refinements are omitted.  I haven't added
       a "deep_save ()" command; it seems unecessary.

    3. Sorry, but I had to move theories/boot into the filter.  There
       are no major changes here, but the directory structure in
       filter has changed significantly.

    4. I added a THEORIES variable to the mk/config file that
       specifies what theories you want to compile.  This means that
       you don't have to edit all the Makefiles when you add a theory,
       and it also means that you can keep your own theories without
       having to commit them to cvs.

I wrote a decideT tactic, similar to Nuprl4 Decide tactic.

We need to prove some decidability rules and add them to the decide_resource
in order to make this tactic useful.

Numerous minor changes.

Added itt_fset: a theory of finite sets based on a list
implementation quotiented by equivalence under arbitrary
occurrences and ordering.

Added initial reflection theory.  Terms are quotiented by
alpha-equality, so normal well-formedness proofs are difficult,
and more work needs to be done to define free variables and

I changed all the obvious places of Nuprl-Light, NL, nl, or any
other instance to MetaPRL, MP, or mp, etc.  The docs may be broken
but I'll fix them soon.  As usual, let me know if anything breaks.

into the Nuprl type theory.

Added license headers to each of the files in preparation for
the first major release.  The license is GNU public license; if
any of you have problems with that, let me know right away.  When
you add new code, you should credit yourself as the author.  When
you modify code, you should add a "Modified by:" to the header,
and possibly a short summary of your changes.

I tried to get the Author lists as correct as I remember, but there
are more than 550 files(!) and I may have made some mistakes. Please
add yourself if I didn't do it right.
