A pattern I find myself repeating a lot: "Test if program is in path, attempt to extend path, list available commands in .\bin." The example here is for LAS Tools, but really it could be anything.

	@echo off
	:: Test if Lastools are in path, if not extend path and try again.
	:: we assume desired tool folder is ".\bin" relative to the batch file
	lasinfo -i >nul 2>&1
	if %errorlevel%==9009 set path=%~dp0\bin;%path%
	lasinfo -i >nul 2>&1
	if not "%errorlevel%"=="1" goto :NoTools

	call :ShowCommands

Print the command line to screen and then execute it. Useful when you want to have echo turned off everywhere else, and not speckle code with `echo on && {cmd line here} && @echo off`

	@echo off
