Using the Tibetan Input Evaluator, eval.exe
------------------------------------------
eval takes two parameters which can be
set in a file called "eval.cfg". This file looks like:

RefPage=5A
Tolerance=28

The "RefPage" parameter indicates the page of the text that
will be used as a reference for the number of lines per page
and the number of characters per line.
The default value (if there is no "eval.cfg" file) is 4A.
It the reference page is never found, eval will warn that the test is invalid.

The "Tolerance" parameter indicates the percent high or low that
the character count of a particular Tibetan line 
can go before a warning is issued. For instance, suppose that
Tolerance is set to 28% as above, and the mean number of characters
per line from the reference page is 200. The eval will issue
a warning if either:
	1) the character count of a line exceeds 128% of 200,
	or 256 characters;
	2) the character count of a line goes below 72% of 200,
	or 144 characters.

eval takes one command line argument, the name of the file to be
analyzed. For instance, to analyze a file called "jewel.txt", type:
	eval jewel.txt

The program produces the following output:

		[First it restates the parameters:]
using: RefPage 5A, Tolerance 28.0 percent
using line count = 7; chars/line 249  from RefPage 5A
		[Then it gives specific page/line warnings:]
!Page 2A: line count: 5  (ref=7)
!Page 6A  Out of Sequence; comes after  5A 
!Page 13A: line count: 6  (ref=7)
!Page 13B:   line 1 too short:    4.0 percent
		[Then it gives total errors:]
--------- Totals for  jewel -----------
165  total Tibetan lines
26  total pages ending with 13B
39662  total characters; 249 chars/line on RefPage  5A
  2  page(s) had incorrect line counts
  1  line(s)   too short
  1  page(s) Out of Sequence
