* Function:
*
* Similar to 'od -cx' but with more concise format
*
* Dump a file in hex and printable on the same line.
* Quick, dirty, works. Non printing chars are displayed
* using the NONPRINT char, and the 16 byte printable is
* delimited by the WALLS char.

* with no restrictions. Sell it if you can find anyone
* dumb enough to buy it.
