[svn-r5125] Purpose:

    feature
Description:
    Added -fsize <fsize> option which controls the family file size
    used.  This can be used to test the file size limits of a machine
    or file system.
Platforms tested:
    modi4 (serial and parallel).  Did not test on other platforms
    because the same code has been tested on the 1.5 branches.
