+  <longdescription lang="en">
+    FFLAS-FFPACK is a library for basic linear algebra operations over
+    a finite field. It is inspired by the BLAS interface (Basic Linear
+    Algebra Subprograms) and the LAPACK library for numerical linear
+    algebra, and shares part of their design. Yet it differs in many
+    aspects due to the specifics of computing over a finite field: it
+    is generic with respect to the finite field, so as to accommodate
+    a large variety of field sizes and implementations; consequently,
+    all routines use C++ template generics and the library is
+    primarily meant to be used as a source code library, to be
+    included and compiled in the user's software.
