- 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.

*** IMPORTANT: before doing "cvs update" see warning below ***

This commit implements a global resource that brings together resource management
that used to be done by each resource in its own way.

- A much simplier object (Mp_resource.resource_info) is now needed to create a new resource.
Additionally, many resource helper modules, such as term_match_table now provide functions
that create a resource_info for you.

- Funtions get_tactic_arg, get_int_tactic_arg, etc were replaced by a single function
get_resource_arg (note: functions for basci types, such as get_with_arg, get_sel_args, etc
were _not_ affected)

- Resource declaration statement now declares and resource creation statement now creates
a function get_<name>_resource. This function ca be passed as a second argument
to get_resource_arg to retrieve the current value of a particular resource.

- Resource annotation functions are now separate from the resource declaration/creation
mechanism. Resource annotation on a rule are now passed to a function named
process_<name>_resource_annotation. This function must have the appropriate
Mp_resource.annotation_processor type for the resource. This function can be declared
and implemented in _any_ module, not just the module that declares and creates the
<name> resource.

- Currenlty MetaPRL leaves it to Ocaml to keep track of these functions.
Consequently the module that defines the process_<name>_resource_annotation function
must be open'ed (not included!) by modules that use <name> annotations.

-----

Unfinished business in this commit:
- Remainder of TODO 1.12 and 1.13

- Some proofs were broken by this commit. It appears that they were broken for
a "good" reason, but still need to be fixed.

- I need to make sure things now always have the right precedences (all things being equal,
the later an item is added to resource, the earlier precedence it should have).

- Consider adding refiner sentinels and display forms to global resource as well.
Currently each of them still does its own way of resource management (although the way
display forms are managed was changed by this commit - need to make sure the precedences
are right).

- Distributed refinement: I am afraid that the current resource code
will either work correctly only if all processes in the distributed group have
the same global resource, or it will attempt to pass around all the resource data.
Obviously, neither of these choices is a good one.

*** WARNING ***

This commit changes the tactic_arg type and also makes minor changes in
the FilterCache.info type. Because of that old .prlb and .cmoz files
*will no longer work*. Old .prla files will work, but will produce lots
of (harmless) Filter_summary.dest_term warning.

Before doing "cvs update" do the following:
1) export all your unsaved proofs into .prla files.
2) rm -f theories/*/*.prlb
3) run "make clean"

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.

 - Fixed a nasty bug in Term_ds.subst - it didn't notice when the same variable
was mentioned several times in the substitution with different terms substituted
for it. This made it possible to break Term_ds invariants leading to all kinds of
strange behaviour.

 - Changed the argument order for "subst" to be more natural

 - Added a subst1 function to substitute for a single variable without having
to put the substitution into a singleton list.

 - Added the resource annotations and updated the rest of the resource code
in CZF so that it now compiles (but I didn't try to expand anything).

This is a major release; I bumped the release number to 0.6.
WARNING: There are major changes here, and there may be problems
   with this version that prevent you from using your old proof.
   Save your work before using this version.
NOTE: If you decide to try this out, and you find problems,
   please(!) send me email so I can fix it.

Changes:
   1. The proof structure is totally changed, so that the proof
      editor edits the raw proof extracts.  This means that you
      can view the actions of the refiner down to the primitive
      rule applications.  In the proof editor, you can use
      "down 0" (or "cd "0") to descend into the proof of a rule box.
      Primitive proofs are called "extracts", and are labeled with
      brackets (like [extract]).  To expand the extract, use the command
      "unfold ()".  You should be able to get all the way down to
      the primitive rule/rewrite applications.

      This also means that the format of the proof files (the .prlb
      files) has changed.  The old proof files are still valid,
      but this is a hack and will be deprecated in the next
      few months.  I haven't yet added Alexey's ASCII proof
      files, but that will come with the next release.

      As usual, the "undo ()" command undoes the last proof step,
      including "unfold ()".  The "nop ()" command, reset the undo
      stack.  I also added a "redo ()" command that undoes the
      last undo.

      There is a simple rule-box proof cache for collecting proofs
      as you edit them.  If cached proofs are available, you will
      see them in brackets (like [* # * *]) on the status line.
      I haven't yet:( added the commands to use cached proofs.

   2. Refiner changes.  I added two new features: the "cutT <term>"
      tactic cuts in a new assumption.  Also, you can apply
      rewrites directly on assumptions, with the "rwc" and
      "rwch" operations, that take a clause argument.  Basically,
      this means that instead of folding the goal, you can unfold
      the assumption.  I believe this is sound; let me know if
      you think otherwise!

   3. Resource changes.  I added resource automation, built on
      the basic resource parsing Alexey added.  Ratherthan writing
      resource code for every rule, you can annotate most rules
      to generate the resource code directly.  You can see lots of
      examples in the Itt theory.  Basically, there are three useful
      resources annotations:
         intro_resource []: adds the rule as an introduction in dT
         intro_resource [SelectOption i]: adds to selT i dT
         elim_resource []: adds as an elimination rule to dT.
            This normally tries to thin the hyp that was eliminated.
         elim_resource [ThinOption]: don't thin the hyp

      Rules should be annotated with labels on their clauses,
      like [wf], [main], [assertion], etc.  This means that in
      most tactic aplcations, you no longer need to have the
      thenLT [addHiddenLabel "main"; ...] part.

      N.B.  This is the most likey parts of this release to
      cause problems, because I deleted most old resource code.

      Also, you can still write standard resource code, but there
      is no longer a d_resource--it has been broken into two parts:
      the intro_resource for application to goals, and elim_resource
      for application to hyps.

   4. The proof editor is multi-threaded, so you can work on multiple
      proofs simultaneously.  In the normal Emacs editor, this is
      no help for you.  But there is a new Java editor with the
      standard point-and-click interface, and it views the proof
      in HTML, with multiple windows etc.  The beautiful thing is
      that you can use display forms to add commands to edit windows.
      The sad thing is that I built it on NT, Java 1.2 is required,
      and I haven't tried the blackdown.org Java release on Linux.
      This editor is pending some bug fixes from Sun to get the
      fonts right (they call this a standard release?).

      In any case, here are the direct implications.  The display
      forms have an "html" mode.  The display form formatting in
      the module Rformat has been completely redone, but display
      _should_ be the same as it was before.

      It is likely that I will add an HTML dump, so we can send
      uneditable proofs around by email or on the web.  Check out
      the file theories/base/summary.ml to see some example HTML
      display forms.

      The other issue: your MetaPRL process starts a web server on
      YOUR local machine using YOUR process id on the "next" available
      TCP port, and it serves files only from the search path that you pass
      MetaPRL.  I realize that this has security implications.  This
      is necessary to get browser access to the working MetaPRL proof.
      Is this crazy?  Let me know your beliefs, religious or
      otherwise.

   5. There are numerous minor changes.  I redid parts of the WeakMemo,
      Term_header_constr, and TermHash.  The theories/tactic directory
      has been split into tactic/boot (which is not compiled by MetaPRL),
      and theories/tactic (which is).

This is the first phase for modifying resources.
The Mp_resource interface has been substantially simplified, but
I believe that it retains as much functionality as it did before
the change.

The next step for me to add the Mp_resource support for
adding resources as rule annotations.

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.

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.

Slightly better Ensemble scheduling.
Native-code compiler has trouble marshaling functions--
its probably a problem with the marshaler.

Added Nl_num, a ML-only implementation of bignums.
This is slower than the C version used by OCaml, but
we can marshal the Nl_nums.  Most of the files changed
are just replacements of Num.* with Nl_num.*.
