what frees the tokens for other uses in non-unicode mode.
For Π, users will have to introduce their own recursive notation.
For λ, this is provided by the -unicode option (which actually is not
documented nor as an option nor in the reference manual; maybe it
should simply be now removed since "Require Import Utf8_core" has the
same effect).

- Added support for recursive notations with binders
- Added support for arbitrary large iterators in recursive notations
- More checks on the use of variables and improved error messages
- Do side-effects in metasyntax only when sure that everything is ok
- Documentation
Note: it seems there were a small bug in match_alist (instances obtained
from matching the first copy of iterator were not propagated).

location dumping for binders uniformly treated in constrintern.ml (and
renamed the optional arg of interp_context from fail_anonymous to
global_level since the flag now also decides whether to dump binders as
global or local ones); added locations for the variables occurring in
the "as in" clauses;

If you want to try, it should be now as simple as:
make clean && ./configure -local -usecamlp4 && make
For the moment, the default stays camlp5, hence
./configure -usecamlp5 and ./configure are equivalent.
Thanks to a suggestion by N. Pouillard, the remaining
incompatibilities are now handled via some token filtering in
camlp4. See compat5*.mlp. Morally, these files should be named .ml4,
but I prefer having them not in $(...ML4) variables, it might confuse
the Makefile... The empty compat5*.ml are used to build empty .cmo
for making camlp5 happy. For camlp4,
- tools/compat5.cmo changes GEXTEND into EXTEND. Safe, always loaded
- tools/compat5b.cmo changes EXTEND into EXTEND Gram. Interact badly with
syntax such that VERNAC EXTEND, we only load it for a few files via
camlp4deps
TODO: check that my quick adaptation of camlp5-specific code in
tactics/extratactics.ml4 is ok. It seems the code by Chung-Kil Hur
is hiding information in the locations ?!

- Instances found by matching.ml now collect the set of bound
variables they possibly depend on in the pattern (see type
Pattern.extended_patvar_map); the variables names are canonically
ordered so that non-linear matching takes actual names into account.
- Removed typing of matching constr instances in advance (in
tacinterp.ml) and did it only at use time (in pretyping.ml). Drawback
is that we may have to re-type several times the same term but it is
necessary for considering terms with locally bound variables of which
we do not keep the type (and if even we had kept the type, we would have
to adjust the indices to the actual context the term occurs).
- A bit of documentation of pattern.mli, matching.mli and pretyping.mli.
- Incidentally add env while printing idtac messages. It seems more correct
and I hope I did not break some intended existing behavior.

The choice between camlp4/5 is done during configure with flags
-usecamlp5 (default for the moment) vs. -usecamlp4.
Currently, to have a full camlp4 compatibility, you need to change
all "EXTEND" and "GEXTEND Gram" into "EXTEND Gram", and change "EOI"
into "`EOI" in grammar entries. I've a sed script that does that
(actually the converse), but I prefer to re-think it and check a few
things before branching this sed into the build mechanism.
lib/compat.ml4 is heavily used to hide incompatibilities between camlp4/5
and try to propose a common interface (cf LexerSig / GrammarSig).
A few incompatible quotations have been turned into underlying code
manually, in order to make the IFDEF CAMLP5 THEN ... ELSE ... END
parsable by both camlp4 and 5. See in particular the fate of
<:str_item< declare ... end >>
Stdpp isn't used anymore, but rather Ploc (hidden behind local module Loc).
This forces to use camlp5 > 5.01.

Cf tok.ml, token isn't anymore string*string where first
string encodes the kind of the token, but rather a nice
sum type. Unfortunately, string*string (a.k.a Plexing.pattern)
is still used in some places of Camlp5, so there's a few
conversions back and forth. But the penalty should be quite low,
and having nicer tokens helps in the forthcoming integration
of support for camlp4 post 3.10

"Fail cmd" is similar to "Time cmd", but instead of printing the execution time,
it reverse the exit status of cmd. "Fail cmd" is successful iff cmd has ended with
an error. This was, we can demonstrate erroneous commands in a script for
pedagogical or testing purpose without having to comment it in order to play the rest
of the script in coqide/PG.
Coq < Fail Foo.
The command has indeed failed with message:
=> Error: Unknown command of the non proof-editing mode.
Coq < Fail Check Prop.
Prop
: Type
Error: The command has not failed !
Two more remarks:
- Fail doesn't catch anomalies.
- Yes it it possible to write things like Fail Fail ... :-)

- Many of them were broken, some of them after Pierre B's rework
of mli for ocamldoc, but not only (many bad annotation, many files
with no svn property about Id, etc)

in a forthcoming git-only setting)

dev/ocamlweb-doc has been erased. I hope no one still use the
"new-parse" it generate.
In dev/,
make html will generate in dev/html/ "clickable version of mlis". (as
the caml standard library)
make coq.pdf will generate nearly the same awfull stuff that coq.ps was.
make {kernel,lib,parsing,..}.{dot,png} will do the dependancy graph of
the given directory.
ocamldoc comment syntax is here :
http://caml.inria.fr/pub/docs/manual-ocaml/manual029.html
The possibility to put graphs in pdf/html seems to be lost.

- exhaustive match for pp_vernac (BeginSubproof, ...)
- for ocamlbuild, remove a spurious cycle in recordops.mli
(unnecessary open of Classops), and fixes of *.itargets and _tags
The compilation via ocamlbuild still need some work, since
plugin firstorder now depends on the new plugin decl_mode

This is a fairly large commit (around 140 files and 7000 lines of code
impacted), it will cause some troubles for sure (I've listed the know
regressions below, there is bound to be more).
At this state of developpement it brings few features to the user, as
the old tactics were
ported with no change. Changes are on the side of the developer mostly.
Here comes a list of the major changes. I will stay brief, but the code
is hopefully well documented so that it is reasonably easy to infer the
details from it.
Feature developer-side:
* Primitives for a "real" refine tactic (generating a goal for each
evar).
* Abstract type of tactics, goals and proofs
* Tactics can act on several goals (formally all the focused goals). An
interesting consequence of this is that the tactical (. ; [ . | ... ])
can be separated in two
tacticals (. ; .) and ( [ . | ... ] ) (although there is a conflict for
this particular syntax). We can also imagine a tactic to reorder the
goals.
* Possibility for a tactic to pass a value to following tactics (a
typical example is
an intro function which tells the following tactics which name it
introduced).
* backtracking primitives for tactics (it is now possible to implement a
tactical '+'
with (a+b);c equivalent to (a;c+b;c) (itself equivalent to
(a;c||b;c)). This is a valuable
tool to implement tactics like "auto" without nowing of the
implementation of tactics.
* A notion of proof modes, which allows to dynamically change the parser
for tactics. It is controlled at user level with the keywords Set
Default Proof Mode (this is the proof mode which is loaded at the start
of each proof) and Proof Mode (switches the proof mode of the current
proof) to control them.
* A new primitive Evd.fold_undefined which operates like an Evd.fold,
except it only goes through the evars whose body is Evar_empty. This is
a common operation throughout the code,
some of the fold-and-test-if-empty occurences have been replaced by
fold_undefined. For now,
it is only implemented as a fold-and-test, but we expect to have some
optimisations coming some day, as there can be a lot of evars in an
evar_map with this new implementation (I've observed a couple of
thousands), whereas there are rarely more than a dozen undefined ones.
Folding being a linear operation, this might result in a significant
speed-up.
* The declarative mode has been moved into the plugins. This is made
possible by the proof mode feature. I tried to document it so that it
can serve as a tutorial for a tactic mode plugin.
Features user-side:
* Unfocus does not go back to the root of the proof if several Focus-s
have been performed.
It only goes back to the point where it was last focused.
* experimental (non-documented) support of keywords
BeginSubproof/EndSubproof:
BeginSubproof focuses on first goal, one can unfocus only with
EndSubproof, and only
if the proof is completed for that goal.
* experimental (non-documented) support for bullets ('+', '-' and '*')
they act as hierarchical BeginSubproof/EndSubproof:
First time one uses '+' (for instance) it focuses on first goal, when
the subproof is
completed, one can use '+' again which unfocuses and focuses on next
first goal.
Meanwhile, one cas use '*' (for instance) to focus more deeply.
Known regressions:
* The xml plugin had some functions related to proof trees. As the
structure of proof changed significantly, they do not work anymore.
* I do not know how to implement info or show script in this new engine.
Actually I don't even know what they were suppose to actually mean in
earlier versions either. I wager they would require some calm thinking
before going back to work.
* Declarative mode not entirely working (in particular proofs by
induction need to be restored).
* A bug in the inversion tactic (observed in some contributions)
* A bug in Program (observed in some contributions)
* Minor change in the 'old' type of tactics causing some contributions
to fail.
* Compilation time takes about 10-15% longer for unknown reasons (I
suspect it might be linked to the fact that I don't perform any
reduction at QED-s, and also to some linear operations on evar_map-s
(see Evd.fold_undefined above)).

- A more clever strategy than the use of null spaces (in revision 12058)
for collapsing multi-byte utf-8 characters into one character
(toplevel.ml, 8.3 and trunk only)
- Fixing discard_to_dot in the presence of iterated lexing failures
- Made the lexer state aligned with the start of utf-8 chars instead
of staying in the middle of multi-byte chars when a token is not
recognized (lexer.ml4)

- make links to section variables working (used qualified names for
disambiguation and fixed the place in intern_var where to dump them)
(wish #2277)
- mapping of physical to logical paths now follows coq (see bug #2274)
(incidentally, it was also incorrectly seeing foobar.v as a in directory foo)
- added links for notations
- added new category "other" for indexing entries not starting with latin letter
(e.g. notations or non-latin identifiers which was otherwise broken)
- protected non-notation strings (from String.v) from utf8 symbol interpretation
- incidentally quoted parseable _ in notations to avoid confusion with
placeholder in the "_ + _" form of notation
- improved several "Sys_error" error messages
- fixed old bug about second dot of ".." being interpreted as regular dot
- removed obsolete lexer in index.mll (and renamed index.mll to index.ml)
- added a test-suite file for testing various features of coqdoc
Things that still do not work:
- when a notation is redefined several times in the same scope, only
the link to the first definition works
- if chars and symbols are not separated in advance, idents
that immediately follow symbols are not detected
(e.g. as in {True}+{True} where coqdoc sees a symbol "+{True}")
- parentheses, curly brackets and semi-colon not linked in notations
Things that can probably be improved:
- all notations are indexed in the same category "other"; can we do better?
- all non-latin identifiers (e.g. Greek letters) are also indexed in the
same "other" category; can we do better?
- globalization data for notations could be compacted (currently there is one
line per each proper location covered by the notation)

- disallow dynamic generation of [case] constructs through [find_scheme]
during a rewrite, as it changes the global environment and subsequent
manipulations of the tactic may use an outdated environment.
- use local exception names so as not to catch and hide unexpected
[Not_found] exceptions.
- fix lifting of constraints for dependent function types
- Allow rewriting on morphisms (terms in function position) even with
[rewrite] (fixes bug #2178).

- This way, the Makefile.build gets shorter and simplier, with a few nasty
hacks removed.
- In particular, we stop creating dummy .ml of .ml4 early "to please ocamldep".
Instead, we now use ocamldep -modules, and process its output via coqdep_boot.
This ways, *.cm* of .ml4 are correctly located, even when some .ml files
aren't generated yet.
- There is no risk of editing the .ml of a .ml4 by mistake, since it is by
default in a binary format (cf pr_o.cmo and variable READABLE_ML4).
M-x next-error still open the right .ml4 at the right location.
- mltop.byteml is now mltop.ml, while mltop.optml keeps its name
- .ml of .ml4 are added to .gitignore

Syntax Include Type is still active, but deprecated, and triggers a warning.
The syntax M <+ M' <+ M'', which performs internally an Include, also
benefits from this: M, M', M'' can be independantly modules or module type.

In trunk the different possible combinations of "at" and "in" with
occurrences are taken into account.
In 8.2 branch, it remains fragile (syntaxes that were accepted remain
accepted and a message warns if the occurrences coming after the
"with" are not taken into account).

Class" too to handle references instead of just idents. Minor fix in
coqdoc. zeta-normalize setoid_rewrite proofs, removing useless
let-bindings generated by the tactic.

- to type patterns w/o losing the information of what subterm is a hole
would need to remember where holes were in "understand", but "understand"
needs sometimes to instantiate evars to ensure the type of an evar
is not its original type but the type of its instance (what can
e.g. lower a universe level); we would need here to update evars
type at the same time we define them but this would need in turn to
check the convertibility of the actual and expected type since otherwise
type-checking constraints may disappear;
- typing pattern is apparently expensive in time; is it worth to do it
for the benefit of pattern-matching compilation and coercion insertion?

We renounced to distribute evars to constr and bindings and to let
tactics do the merge. There are now two disciplines:
- the general case is that the holes in tactic arguments are pushed to
the general sigma of the goal so that tactics have no such low-level
tclEVARS, Evd.merge, or check_evars to do:
- what takes tclEVARS and check_evars in charge is now a new
tactical of name tclWITHHOLES (this tactical has a flag to support
tactics in either the "e"- mode and the non "e"- mode);
- the merge of goal evars and holes is now done generically at
interpretation time (in tacinterp) and as a side-effect it also
anticipates the possibility to refer to evars of the goal in the
arguments;
- with this approach, we don't need such constr/open_constr or
bindings/ebindings variants and we can get rid of all ugly
inj_open-style coercions;
- some tactics however needs to have the exact subset of holes known;
this is the case e.g. of "rewrite !c" which morally reevaluates c at
each new rewriting step; this kind of tactics still receive a
specific sigma around their arguments and they have to merge evars
and call tclWITHHOLES by themselves.
Changes so that each specific tactics can take benefit of this generic
support remain to be done.
