+    (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:
+@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).")
