+    (description
+     "ForUtils is a modern Fortran utility library that provides essential
+tools for scientific computing and data processing.  It offers Python-like
+convenience functions and object-oriented interfaces for common programming
+tasks in Fortran 2003/2008 programs.
+
+Key Features:
+
+@itemize
+@item ArrayUtils - find (minimal/maximal) index of an element in an array
+@item FileUtils - classes for handling file access, python-like
+loadtxt/savetxt functions
+@item IniObjects - read/write name=value configuration files with inheritance,
+array and default value support
+@item MatrixUtils - read/write matrices and interface to some BLAS/LAPACK
+routines
+@item MiscUtils - utility functions for optional arguments
+@item MpiUtils - wrappers for MPI-routines to compile with(out) MPI library
+@item ObjectLists - lists of arbitrary objects including specializations for
+vectors
+@item RandUtils - some functions to generate random numbers
+@item RangeUtils - maintain sets of equally spaced intervals, e.g. for
+integration ranges
+@item StringUtils - utilities for strings, like concat of distinct types
+a.s.o.
