SGI DAT Goodies, version 1.0

This is a simple set of DAT examples. There are three programs here, 
dodat, verifydat, and cdtodat. Dodat is a simple scripting language
that lets you read & write files to DAT tapes in a frame-accurate 
manner, so you can master your own DATs, or grab just a certain chunk of
audio off DAT or whatever. cdtodat will copy a CD to DAT. verifydat will 
read the timecode on a DAT and make sure that it is continuous and conforms 
to the DAT spec as I understand it. Each has its own README file with more
complete information. In the course of writing these examples, I tried
to make them useful little tools for DAT stuff, but they are by no means
intended as complete and professional solutions for DAT audio. They are
supplied as-is and without warranty of any kind.

Note that the current firmware (2.63) has some bugs in it which make
some operations difficult. (The manufacturer of the drives is aware of
these and intends to fix the problems in newer firmware). These are:

1) writes following seeks are not always frame-accurate.
2) writes following reads are not frame-accurate.
3) The read-position command does not return the correct position (there
   is an easy workaround for this in dodat).
4) The tape drive unloads the tape from the heads after a minute of idle
   time. This will cause immediately subsequent reads to return bad data 
   (this has been fixed in newer firmware).

I hope you enjoy these programs. Comments, bug reports, additions, etc.
are welcome.
