/**
* VOTDUMP
*
* Example program to convert a VOTable to a delimited file, ...the long way.
*
* Usage:
* votdump [-b|-c|-s|-t] <votable>
*
* Where
* -b use '|' as the delimiter (Bar)
* -c use ',' as the delimiter (CSV)
* -s use ' ' as the delimiter (space-delimited)
* -t use '\t' as the delimiter (TSV)
*
* <votable> Name of file to dump, or '-' for stding
