(* This module manages customization parameters at the vernacular level *)
(* Two kinds of things are managed : tables and options value
- Tables are created by applying the [MakeTable] functor.
- Variables storing options value are created by applying one of the
[declare_int_option], [declare_bool_option], ... functions.
Each table/option is uniquely identified by a key of type [option_name]
which consists in a list of strings. Note that for parsing constraints,
table names must not be made of more than 2 strings while option names
can be of arbitrary length.
The declaration of a table, say of name [["Toto";"Titi"]]
automatically makes available the following vernacular commands:
Add Toto Titi foo.
Remove Toto Titi foo.
Print Toto Titi.
Test Toto Titi.
The declaration of a non boolean option value, say of name
[["Tata";"Tutu";"Titi"]], automatically makes available the
following vernacular commands:
Set Tata Tutu Titi val.
Print Table Tata Tutu Titi.
If it is the declaration of a boolean value, the following
vernacular commands are made available:
Set Tata Tutu Titi.
Unset Tata Tutu Titi.
Print Table Tata Tutu Titi. (* synonym: Test Table Tata Tutu Titi. *)
The created table/option may be declared synchronous or not
(synchronous = consistent with the resetting commands) *)

(* The functor [MakeStringTable] declares a table containing objects
of type [string]; the function [member_message] say what to print
when invoking the "Test Toto Titi foo." command; at the end [title]
is the table name printed when invoking the "Print Toto Titi."
command; [active] is roughly the internal version of the vernacular
"Test ...": it tells if a given object is in the table; [elements]
returns the list of elements of the table *)

(* The functor [MakeRefTable] declares a new table of objects of type
[A.t] practically denoted by [reference]; the encoding function
[encode : reference -> A.t] is typically a globalization function,
possibly with some restriction checks; the function
[member_message] say what to print when invoking the "Test Toto
Titi foo." command; at the end [title] is the table name printed
when invoking the "Print Toto Titi." command; [active] is roughly
the internal version of the vernacular "Test ...": it tells if a
given object is in the table. *)
