- 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)
- Useless for those of us that work with git-svn (and a fortiori
in a forthcoming git-only setting)
- Even in svn, they seem to be of little interest

variables with syntax:
[Local?|Global] Generalizable Variable(s)? [all|none|id1 idn].
By default no variable is generalizable, so this patch breaks backward
compatibility with files that used implicit generalization (through
Instance declarations for example). To get back the old behavior, one
just needs to use [Global Generalizable Variables all].
Make coq_makefile more robust using [mkdir -p].

1) compilation of Library.tex was failing on a "Ext_" in Diaconescu.v
In fact coqdoc was trying to recognize the end of a _emphasis_ and
hence inserted a bogus }. For the moment I've enclosed the phrase
with [ ], but this emphasis "feature" of coqdoc seems _really_
easy to broke. Matthieu ?
2) By the way, this Library document was made from latin1 and utf8
source file, hence bogus characters. All .v containing special
characters are converted to utf8, and their first line is now
mentionning this. (+ killed some old french comments and some
other avoidable special characters).
PLEASE: let's stick to this convention and avoid latin1, at least
in .v files.

rewriting (thanks to Georges Gonthier for pointing it out).
We try to find a declared rewrite relation when the equation does not
look like an equality and otherwise try to reduce it to find a leibniz equality
but don't backtrack on generalized rewriting if this fails. This new
behavior make two fsets scripts fail as they are trying to use an
underlying leibniz equality for a declared rewrite relation, a [red]
fixes it.
Do some renaming from "setoid" to "rewrite".
Fix [is_applied_rewrite_relation]'s bad handling of evars and the
environment.
Fix some [dual] hints in RelationClasses.v and assert that any declared
[Equivalence] can be considered a [RewriteRelation].
Fix minor tex output problem in coqdoc.

guessing the binding name by default and making all generalized
variables implicit. At the same time, continue refactoring of
Record/Class/Inductive etc.., getting rid of [VernacRecord]
definitively. The AST is not completely satisfying, but leaning towards
Record/Class as restrictions of inductive (Arnaud, anyone ?).
Now, [Class] declaration bodies are either of the form [meth : type] or
[{ meth : type ; ... }], distinguishing singleton "definitional" classes
and inductive classes based on records. The constructor syntax is
accepted ([meth1 : type1 | meth1 : type2]) but raises an error
immediately, as support for defining a class by a general inductive type
is not there yet (this is a bugfix!).

Now there is a class "SetoidRelation" for registering relations that
should always be considered as setoids and never unfolded. Every "Add
Relation" command adds an instance and impl,iff are there by
default. Now the test is: if there is a SetoidRelation instance, use it
; otherwise, allow unfolding to find an eq or fallback on
setoid_rewrite. To avoid searching for SetoidRelation instances
repeateadly we check that it is really needed first by unfolding the
hyp. Only two scripts relied on the now-forbidden semantics of rewriting
by an @eq inside a setoid relation, in Numbers.

- Now [ id : Class foo ] makes id an explicit argument,
and [ Class foo ] is equivalent to [ {someid} : Class foo ].
This makes declarations such as "Class Ord [ eq : Eq a ]" have
sensible implicit args.
- Better handling of {} in class and record declarations, refactorize
code for declaring structures and classes.
- Fix merging of implicit arguments information on section closing.

change the default pretty-printing to use Π, λ instead of
forall and fun (and allow "," as well as "=>" for "fun" to be more
consistent with the standard forall and exists syntax). Parsing allows
theses new forms too, even if not in -unicode, and does not make Π or
λ keywords. As usual, criticism and suggestions are welcome :)
Not sure what to do about "->"/"→" ?
- [setoid_replace by] now uses tactic3() to get the right parsing level
for tactics.
- Type class [Instance] names are now mandatory.
- Document [rewrite at/by] and fix parsing of occs to support their
combination.
- Backtrack on [Enriching] modifier, now used exclusively in the
implementation of implicit arguments.

relf/sym/trans relations from morphisms on prop connectives and
relations.
- Add general order theory on predicates, instantiated for relations.
Derives equivalence, implication, conjunction and disjunction as
liftings from propositional connectives. Can be used for n-ary
homogeneous predicates thanks to a bit of metaprogramming with lists of
types.
- Rebind Setoid_Theory to use the Equivalence record type instead of
declaring an isomorphic one. One needs to do "red" after constructor to
get the same statements when building objects of type Setoid_Theory, so
scripts break.

symmetric... classes for now, merging Relations with RelationClasses
requires some non-trivial changes on implicits but also some definitions
are different (e.g. antisymmetric in Classes is defined w.r.t an
equivalence relation and not eq). Move back to Reflexive and so on.
reflexivity-like tactics fail in the same way as before if Setoid was
not imported. There is now a scope for morphism signatures, hence "==>",
"++>" and "-->" can be given different interpretations.

names, gives the ability to specify qualified classes in instance
declarations. Use that in the class_tactics code.
Refine the implementation of classes. For singleton classes the
implementation of the class becomes a regular definition (into Type or
Prop). The single method becomes a 'trivial' projection that allows to
launch typeclass resolution. Each instance is just a definition as
usual. Examples in theories/Classes/RelationClasses. This permits to
define [Class reflexive A (R : relation A) := refl : forall x, R x
x.]. The definition of [reflexive] that is generated is the same as the
original one. We just need a way to declare arbitrary lemmas as
instances of a particular class to retrofit existing reflexivity lemmas
as typeclass instances of the [reflexive] class.
Also debug rewriting under binders in setoid_rewrite to allow rewriting
with lemmas which capture the bound variables when applied (works only
with setoid_rewrite, as rewrite first matches the lemma with the entire,
closed term). One can rewrite with [H : forall x, R (f x) (g x)] in the goal
[exists x, P (f x)].

implicits for left, inl or eq, hence some theories had to be changed
again. It should make some user contribs compile again too. Also
do not import functional extensionality when importing Program.Basics,
add a Combinators file for proofs requiring it and a Syntax file for the
implicit settings. Move Classes.Relations to Classes.RelationClasses to
avoid name clash warnings as advised by Hugo and Pierre.

implementation. Mostly syntax changes when declaring parametric
relations, but also some declarations were relying on "default"
relations on some carrier. Added a new DefaultRelation type class that
allows to do that, falling back to the last declared Equivalence
relation by default. This will be bound to Add Relation in the next
commit.
Also, move the "left" and "right" notations in Program.Utils to "in_left" and
"in_right" to avoid clashes with existing scripts.
Minor change to record to allow choosing the name of the argument for
the record in projections to avoid possible incompatibilities.

binding, add "!" syntax for the new binders which require parameters and
not superclasses. Change backquotes for curly braces for user-given
implicit arguments, following tradition. This requires a hack a la
lpar-id-coloneq. Change ident to global for typeclass names in class
binders. Also requires a similar hack to distinguish between [ C t1 tn ]
and [ c : C t1 tn ]. Update affected theories.
While hacking the parsing of { wf }, factorized the two versions of fix
annotation parsing that were present in g_constr and g_vernac.
Add the possibility of the user optionaly giving the priority for resolve and
exact hints (used by type classes). Syntax not fixed yet: a natural
after the list of lemmas in "Hint Resolve" syntax, a natural after a "|"
after the instance constraint in Instance declarations (ex in
Morphisms.v).

Tabareau:
- first pass: generation of the Morphism constraints with metavariables
for unspecified relations by one fold over the term.
This builds a "respect" proof term for the whole term with holes.
- second pass: constraint solving of the evars, taking care of finding a
solution for all the evars at once.
- third step: normalize proof term by found evars, apply it, done!
Works with any relation, currently not as efficient as it could be due
to bad handling of evars. Also needs some fine tuning of the instances
declared in Morphisms.v that are used during proof search, e.g. using
priorities.
Reorganize Classes.* accordingly, separating the setoids in
Classes.SetoidClass from the general morphisms in Classes.Morphisms
and the generally applicable relation theory in Classes.Relations.

for basic functional programming and relation
definitions respectively.
Classes.Relations also includes the definition of Morphism
and instances for the standard morphisms and relations (eq, iff, impl,
inverse and complement). The class_setoid.ml4 [setoid_rewrite] tactic
has been reimplemented on top of these definitions, hence it doesn't
require a setoid implementation anymore. It also generates obligations
for missing reflexivity proofs, like the current setoid_rewrite. It has
not been tested on large examples but it should handle directions and
occurences. Works with in if no obligations are generated at this time.
What's missing is being able to rewrite by a lemma instead of a simple
hypothesis with no premises.

The initial Type Classes patch.
This patch introduces type classes and instance definitions a la Haskell.
Technically, it uses the implicit arguments mechanism which was extended a bit.
The patch also introduces a notation for explicitely marking implicit, maximally inserted parameters.
It includes the tactic redefinition code too (Ltac tac ::= foo redefines tac).

Generalize usage of implicit arguments in terms, up to rawconstr. Binders are decorated with binding info, either Implicit or Explicit for rawconstr. Factorizes code for typeclasses, topconstrs decorations are Default (impl|expl) or TypeClass (impl|expl) and
implicit quantification is resolve at internalization time, getting rid of the arbitrary prenex restriction on contexts.
