A test file is just an Imlac assembler source file with special comments that
define tests to be performed. For example:
```
; test file
org 0100
law 1
hlt
end
;! 0100 004001
;! 0101 000000
```
::
; test file
org 0100
law 1
hlt
end
;! 0100 004001
;! 0101 000000
The special test comments have **';!** in column 1. Normal comments may also
exist in the file. Here the test comments are:
```
;! 0100 004001
;! 0101 000000
```
::
;! 0100 004001
;! 0101 000000
which tells **test_harness** to check that the PTP file generated by the
assembler does load *004001* at address *0100*, etc.

test_harness Usage
==================
```
Usage: test_harness [ -h ] [ -d <directory> ] [ -p <prefix> ]
::
Where <prefix> is the test filename prefix of files to test,
<directory> is a directory of test files.
If <directory> is specified run tests in that directory. If not specified
the test directory is assumed to be './tests'.
If <prefix> is specified, run tests on files in the test subdirectory with
a filename of <prefix>* . If <prefix> is not specified all files are tested.
