    (description
     "fplll contains implementations of several lattice algorithms.
The implementation relies on floating-point orthogonalization, and LLL
is central to the code, hence the name.

It includes implementations of floating-point LLL reduction
algorithms, offering different speed/guarantees ratios.  It contains
a @emph{wrapper} choosing the estimated best sequence of variants in
order to provide a guaranteed output as fast as possible.  In the case
of the wrapper, the succession of variants is oblivious to the user.

It includes an implementation of the BKZ reduction algorithm,
including the BKZ-2.0 improvements (extreme enumeration
pruning, pre-processing of blocks, early termination).  Additionally,
Slide reduction and self dual BKZ are supported.

It also includes a floating-point implementation of the
Kannan-Fincke-Pohst algorithm that finds a shortest non-zero lattice
vector.  For the same task, the GaussSieve algorithm is also available
in fplll.  Finally, it contains a variant of the enumeration algorithm
that computes a lattice vector closest to a given vector belonging to
the real span of the lattice.")

    (description
     "IML is a C library implementing algorithms for computing exact
solutions to dense systems of linear equations over the integers.
Currently, IML provides the following functionality:

@itemize
@item Nonsingular rational system solving:
compute the unique rational solution X to the system AX=B, where A and B
are integer matrices, A nonsingular.
@item Compute the right nullspace or kernel of an integer matrix.
@item Certified linear system solving:
compute a minimal denominator solution x to a system Ax=b, where b is an
integer vector and A is an integer matrix with arbitrary shape and
rank profile.
@end itemize

In addition, IML provides some low level routines for a variety of mod p
matrix operations: computing the row-echelon form, determinant, rank
profile, and inverse of a mod p matrix. These mod p routines are not
general purpose; they require that p satisfy some preconditions based on
the dimension of the input matrix (usually p should be prime and should be
no more than about 20 bits long).")
