/*-------------------------------------------------------------------------
* 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
*
* Date: May 9, 2003
*
* Comments:
*
* Modifications: July 2004
* Introduced the four modes:
* Normal mode: print the number of differences found and where they occurred
* 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
*
* October 2005
* Introduced a new field 'not_cmp' to 'diff_opt_t' that detects
* if some objects are not comparable and prints the message
* "Some objects are not comparable"
*
* February 2007
* Added comparison for dataset regions.
* Added support for reading and comparing by hyperslabs for large files.
* Inclusion of a relative error formula to compare floating
* point numbers in order to deal with floating point uncertainty.
* Printing of dataset dimensions along with dataset name
*
* November 19, 2007
* adopted the syntax h5diff [OPTIONS] file1 file2 [obj1[obj2]]
