- Added an option to be have "THEORIES=all" in mk/config
(instead of THEORIES="long list of theories").
I will change all my nightly scripts to use THEORIES=all.

- Added mc to the default list of TEXTHEORIES. Added a file all-bodies.tex
that would automatically contain \inputs corresponding to TEXTHEORIES.
(Before this change we had to update all-theories.tex by hands whenever TEXTHEORIES
was changed).

- Minor fixes in some display forms.

- Removed theories/caml that never had anything useful.

- Removed a few files from theories/ocaml_doc that seemed to be there by accident
(Jason, can you confirm?).

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

- All rules in record theories are prooved (except some simple arith facts).

- Now progressT checks whether the assumptions are changed (not only the goal).

- Add a new operator tsquash{A}={Top|A}

I joined Itt_hide and Itt_squash into a single theory - Itt_squash that deals
with both the meta-level squash operator (Base_trivial!squash{}) and the type
theory squash operator (Itt_squash!squash{'A}). This makes sense because
these two operators are almost exectly the same in nature except for oe
being a meta-level operator and another - an object-level one.

This commit also renames Itt_hide!hide into Itt_squash!squash. This means
that we now have two operators named "squash", however this should not cause
any confusion since all part of the system (including the parser and display
form mechanism) take into account the number of arguments.

Warning: This commit probably broke lots of proofs. I plan to fix that
after I have a chance to rewrite the squash theory a little better (for
now I just copied the one from Itt_hide). Hopefully, I should have it
done within a week.

For now 'a~'b produces Itt_squiggle!sqeq{'a;'b} rather then Perv!rewrite.

I documented the Itt_squiggle theory (see all-theories.pdf).

I have added a new theory Itt_struct2 with some derived advanced versions of
substitution rules and the cut rule.
In particular, I have proved the let (cutEq) rule (that is the cut rule for the membership).

Itt_struct2 redefines the substT tactic to use stronger substitution rules.
There are also new tactics: letT, assetEqT and assertHideT.

Itt_theory does not include Itt_struct2. If you whant to use these rules, you need to include
Itt_struct2 explicitly.

I split the Itt_set theory into Itt_hide and Itt_set.
Note that now the term hide declared in Itt_hide theory, not in Itt_set.
Let me know if you have problems with this.

Now hide(A) is a full-fledged type.
We can use it not only for hiding hypothesis,
but also anywhere in a sequent.

By definition hide(A) is empty if A is empty and has only one
element "it" otherwise.

This jumbo update is a documentation update.  There are no
logical changes.  I did two things:

1. First, comments that begin with the sequence "(*!" are
   interpreted as structured comments.  The contents are parsed
   as terms, and the comments will display in the editor window.
   The comments may contain arbitrary text, as usual, and they
   can also contain explicit terms.  The syntax for terms is:

   @opname[p1, ..., pn]{t1; ...; tm}

   or there is an alternate syntax:

   @begin[opname, p1, ..., pn]
   arg
   @end[opname]

   Text sequences count as a single term.  So, for instance, the
   term @bf{Hello world} display the "Hello world" text in a bold
   font.

   The "doc" term is used for text that is considered to be
   documentation.  There is a set of LaTeX-like terms that you can
   use to produce good-looking documentation.  These are all
   documented in the theories/tactic/comment.ml module.  The exact
   syntax of structured comments is defined in the
   mllib/comment_parse.mll file.  You can also look at any of the
   module in the theories/itt directory if you want to see examples.

   You can generate a pritable version of documentation with the
   print_theory command in the editor.  For example, the command

   # print_theory "itt_equal";;

   produces a file called output.tex that can be formatted with
   your favorite version of latex2e.  You can also generate a
   manule of all the theories by running "make tex" in the
   editor/ml directory.  Or you can run "make" in the
   doc/latex/theories directory.

   The files are hyperlinked, and they contain a table of contents
   and an index.  The preferred reader is acrobat, and the preferred
   formatter is pdflatex.

2. Second, I documented the tactic, base, itt, and czf theories.

3. Oh, and I also added a spelling checker:)  You can turn on the
   spelling checker with the -debug spell option or MP_DEBUG=spell.
   If prlc thinks that your files contain spelling mistakes, it will
   print them out and abort.  You can fix this problem by 1) fixing
   the spelling error, 2) adding the words withing a @spelling{words}
   term in a comment, or adding the words to you .ispell_english
   directory.

   For example, we could either do this:

   @begin[spelling]
   Aleksey Nogin
   @end[spelling]

   Or we could just add Alexey to either $cwd/.ispell_english, or
   ~/.ispell_english.

   The spell checker uses /usr/dict/words as a database, which it
   compiles to a hashtable in /tmp/metaprl-spell-$USER.dat.  Don't
   worry about the tmp file, it is generated automatically.
