     "Gflags is a C++ library to parse command-line flags.  It differs from
other such libraries in that command-line flag definitions can be scattered
around the source code, and not just listed in one place such as @code{main}.
This means that a single source-code file will define and use flags that are
meaningful to that file.  Any application that links in that file will get the
flags, and the gflags library will automatically handle that flag
appropriately.")

     "GNU Gengetopt is a program to generate a C/C++ function for parsing
command-line options using the getopt_long function found in GNU
libc, removing some of the tedium of this task for large programs
that accept many options.  The options parsed by the generated
function may be in both short (e.g., \"-h\") and long (\"--help\")
formats, as specified by the GNU coding standards.  Additionally, the
output of the standard options \"--help\" and \"--version\" is generated
automatically.")
