=head1   runsqlcmd 



 This script is called to run the sql statements found in the files
   in either the default /opt/xcat/lib/perl/xCAT_schema  or the
   directory input with the -d flag.
   For more information see man runsqlcmd and the
   developers guide:
   http://xcat.svn.sourceforge.net/viewvc/xcat/xcat-core/trunk/xCAT-client/share/doc/xCAT2DevGuide.pdf
