/*
* getFormat
*
* Program that computes the rrd_format structures for Cricket Arch.
*
* To compile:
* gcc -I<path to RRD Tool's src dir> -o getFormat getFormat.c
*
* I make an assumptions that the unival unions arrays are linear and there
* is NO padding other than the normal padding for unions and that the double
* value of the union is bigger than the unsigned long...
*
* Contributed by Ed Bugg <Bugge@ABCBS.com>. Bug fixes by Melissa
* D. Binde <binde@amazon.com> and Jeff Allen <jra@corp.webtv.net>.
