Constructors, Assignment and Destructor
int	ppl_new_Congruence_System (ppl_Congruence_System_t *pcs)
	Builds an empty system of congruences and writes a handle to it at address `pcs`.

int	ppl_new_Congruence_System_zero_dim_empty (ppl_Congruence_System_t *pcs)
	Builds a zero-dimensional, unsatisfiable congruence system and writes a handle to it at address `pcs`.

int	ppl_new_Congruence_System_from_Congruence (ppl_Congruence_System_t *pcs, ppl_const_Congruence_t c)
	Builds the singleton congruence system containing only a copy of congruence `c`; writes a handle for the newly created system at address `pcs`.

int	ppl_new_Congruence_System_from_Congruence_System (ppl_Congruence_System_t *pcs, ppl_const_Congruence_System_t cs)
	Builds a congruence system that is a copy of `cs`; writes a handle for the newly created system at address `pcs`.

int	ppl_assign_Congruence_System_from_Congruence_System (ppl_Congruence_System_t dst, ppl_const_Congruence_System_t src)
	Assigns a copy of the congruence system `src` to `dst`.

int	ppl_delete_Congruence_System (ppl_const_Congruence_System_t cs)
	Invalidates the handle `cs:` this makes sure the corresponding resources will eventually be released.

Functions that Do Not Modify the Congruence System
int	ppl_Congruence_System_space_dimension (ppl_const_Congruence_System_t cs, ppl_dimension_type *m)
	Writes to `m` the dimension of the vector space enclosing `cs`.

int	ppl_Congruence_System_empty (ppl_const_Congruence_System_t cs)
	Returns a positive integer if `cs` contains no (non-trivial) congruence; returns 0 otherwise.

int	ppl_Congruence_System_begin (ppl_const_Congruence_System_t cs, ppl_Congruence_System_const_iterator_t cit)
	Assigns to `cit` a const iterator "pointing" to the beginning of the congruence system `cs`.

int	ppl_Congruence_System_end (ppl_const_Congruence_System_t cs, ppl_Congruence_System_const_iterator_t cit)
	Assigns to `cit` a const iterator "pointing" past the end of the congruence system `cs`.

int	ppl_Congruence_System_OK (ppl_const_Congruence_System_t cs)
	Returns a positive integer if `cs` is well formed, i.e., if it satisfies all its implementation invariants; returns 0 and perhaps makes some noise if `cs` is broken. Useful for debugging purposes.

Functions that May Modify the Congruence System
int	ppl_Congruence_System_clear (ppl_Congruence_System_t cs)
	Removes all the congruences from the congruence system `cs` and sets its space dimension to 0.

int	ppl_Congruence_System_insert_Congruence (ppl_Congruence_System_t cs, ppl_const_Congruence_t c)
	Inserts a copy of the congruence `c` into `cs`; the space dimension is increased, if necessary.

Input/Output Functions
int	ppl_io_print_Congruence_System (ppl_const_Congruence_System_t x)
	Prints `x` to `stdout`.

int	ppl_io_fprint_Congruence_System (FILE *stream, ppl_const_Congruence_System_t x)
	Prints `x` to the given output `stream`.

int	ppl_io_asprint_Congruence_System (char **strp, ppl_const_Congruence_System_t x)
	Prints `x` to a malloc-allocated string, a pointer to which is returned via `strp`.

int	ppl_Congruence_System_ascii_dump (ppl_const_Congruence_System_t x, FILE *stream)
	Dumps an ascii representation of `x` on `stream`.

int	ppl_Congruence_System_ascii_load (ppl_Congruence_System_t x, FILE *stream)
	Loads an ascii representation of `x` from `stream`.
