/*-------------------------------------------------------------------------
 * Function: main
 *
 * Purpose: h5diff main program
 *
 * Return: An  exit status of 0 means no differences were found, 1 means some
 *   differences were found.
 *
 * Programmer: Pedro Vicente, pvn@ncsa.uiuc.edu
 *
 * Date: May 9, 2003
 *
 * Comments:
 *
 * Modifications: July 2004
 *  Introduced the four modes:
 *   Normal mode: print the number of differences found and where they occured
 *   Report mode: print the above plus the differences
 *   Verbose mode: print the above plus a list of objects and warnings
 *   Quiet mode: do not print output
 *
 * November 2004: Leon Arber (larber@uiuc.edu)
 *     Additions that allow h5diff to be run in parallel
 *
 * February 2005: Leon Arber (larber@uiuc.edu)
 *   h5diff and ph5diff split into two files, one that is used
 *   to build a serial h5diff and one used to build a parallel h5diff
 *   Common functions have been moved to h5diff_common.c
