- 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.

Code cleanup:

I looked (using the code I've put into macro.ml) for places where the same code
appeared in several branches of a match or function expression. I changed those
places to use a complex pattern and a single copy of the code.

- Merged the Ocaml 3.02 changes

- Now http server is compiled in by default, but is only started if
the "-http true" argument is passed or MP_HTTP environment variable
is set to "true".

- A few other minor changes.

*** 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"

- Changed the syntax of resource implementation. Now you no longer need to
re-declare resource types in the implementation. Instead of the declaration
and a Mp_resource.create call, use the following syntax in the implementation:

let resource <name> = <expr>

where <expr> is an expression that of the type Mp_resource.info

- Additionally, it is no longer necessary to use _resource in resource names
and resource annotations.

1) Proved some *Formation rules that used to be primitive (using in part
Alexei's cut rule idea). We should probably continue this job and
eliminate "primitiveness" from as much Formation rules as we can.

2) unitSqequal rule should be primitive

3) mk: don't pass -j1 to make when MAKE_JOBS = 1

4) In MP toploop, when a non-negatice integer is found where
an address was expected, that integer is considered to be
the hypothesis number. This enables applying primitive rules
from the MP toploop.

Rules are automatically added to mptop toploop.  This just means
that you can use a rule directly in a tactic without having to wrap
it.  Rules require addresses, so they are still hard to use, but
at least they are accessible.

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.

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
substitution.
