#@REM A convenient run one test giving the number and expected exit
#@REM
#@REM This is to run just one, like "t1 1642186-1 0"
#@REM
#@REM Note it uses a relative path to the built exe file, and
#@REM expects the ouput folder has to exist.
#@REM
#@REM Obviously you may want to adjust this file, like seen below to test
#@REM different versions of tidy.exe...
#@REM Rather than altering this file, which will be flagged by git,
#@REM I copy it to say a temp1.bat, and modify that to suit my testing
#@REM
#@REM There is also an 'alltest.cmd' which runs some 227 tests that 
#@REM gets the case listed in 'testcases.txt' file.
