interstingly, i considered mentioning the old upas/fs trick of the info
file, which i believe is approximately the same hack.  the "xxx" hack
i recently added to the file has table of upas/fs is somewhat the

i suppose that in the language of standardized assessment tests
technique is to hack as 30x is to 5%.
