[boost] Re: Formal Review: Command Line & Config library

I can't link much of the sample code shown in the documentation.

In particular, I tried compiling the code included in the section titled 
"Variables map", with gcc3.2.2.  I got the link error:

     test2.cpp:40: undefined reference to 
`boost::program_options::variables_map::variables_map[in-charge]()'

The error message references this line of code:

     po::variables_map vm;

Bere's the script I run to compile the code:

     #!/bin/bash

     BOOST=../../../src/pub/boost_1_30_0
     LIBSRC=$BOOST/libs/program_options/src

     g++  -I$BOOST -c test2.cpp
     g++  -I$BOOST -c $LIBSRC/cmdline.cpp
     g++  -I$BOOST -c $LIBSRC/config_file.cpp
     g++  -I$BOOST -c $LIBSRC/options_description.cpp
     g++  -I$BOOST -c $LIBSRC/parsers.cpp

     g++  -o test2  test2.o cmdline.o config_file.o 
options_description.o parsers.o

Comment: it would be helpful to show examples of using the sample 
programs which are given in the documentation, along with expected output.
