 * Desc: Skeleton driver for a binary-file dumper program. 
 * 
 * This file is a generic skeleton for a binary-file dumper, 
 * it dumps all the information it finds about sections in the
 * file, and it displays any code sections in raw hexadecimal 
 * notation.

 *    Apr 01 - Cristina: Created
 * 11 May 01 - Nathan: Print text section name (suppresses warning)
 * 11 May 01 - Mike: use bCode (prints text section of hppa binaries)
