SUPPORTED COMMAND LINE FLAGS
----------------------------

	-f	The frequency of the TV channel to use. YOU NEED TO KNOW THIS.
	-p	The page number you want to pull in. 3 digits, 100 being the
		lowest.
	-s	The subpage you want to pull in. 2 digits with 01 being the 
		lowest. The highest i've seen is about 60.
	-r	The RAW toggle. You get raw viewdata output if you use this 
		flag. Maybe useful if you have a viewdata viewer.
	-o	The output filename. I've allowed 256 characters for this. It
		should be enough. If you don't specify this you get the pages
		printed to stdout. 

EXAMPLE
-------

teletext -f 2d81 -p 100 -s 01 -o ch4p100sp1.txt

CHANGES
-------
0.1	1st version. Got it to pull a page in in at a specified frequency.
	No error checking etc. Just a quick hack to get it to work.

0.2	I've just added support for subpages, raw data and output files.
	Still no error checking. It's still a hack. 

TODO
----
Well it's a hack as of rev 0.2 (17/10/96) but it works. I'll start to think 
about organizing it into a more structured piece of software.

Start to think about some scripts to pull specific pages in. How should I 
organize this?

FREQUENCIES
-----------
Here are some frequencies (MHz) that I use in London in the UK.
567.12
542.992
510.925
487.381

The frequencies can be turned into the hex values required for the OPT III
teletext adapter by using the following equation.

                Integer = (MHz + 39.5) * 20

			12132
			11650
			11008
			10538

Then you turn the integer into a hex value.

			2f64
			2d82
			2b00
			292a

This is the value you give to the teletext software as the frequency value.
At some point in the future I'll make it clever enough to parse a floating point
frequency value, but i'm going for simplicity just now.
