Request for Test on Mac: Wrapper function for LrTask.execute

Question

Hi,
I've written some basic wrapper functions for LrTasks.execute to handle spaces. I've tested that stuff with windows xp and exiftool and would like to ask you to test it for mac os and perhaps win 7 with whatever command. Is that possible?

In the zip file you will find the basic classes and some description but no info.lua or a special test script (sry for that). You can call it like:
     local args = {"-@", inputFileName, imageFileName}
     local redirect = {}
     redirect.stdout = LrPathUtils.getStandardFilePath('temp') .. "exiftool.stdout"
     redirect.stderr = LrPathUtils.getStandardFilePath('temp') .. "exiftool.stderr"
     local result = LZA_System.execute(pathToExiftool, args, redirect)
     logger:info("result.formatedCmd: " .. tostring(result.formatedCmd))
     logger:info("result.returnCode: " .. tostring(result.returnCode))
     logger:info("result.success: " .. tostring(result.success))
     logger:info("result.stdout: " .. tostring(result.stdout))
     logger:info("result.stderr: " .. tostring(result.stderr))
Example is not runable!
Kind regards

Link did not work for me: http://www.daten-transport.de/?id=sZM3EuEEpwx7 - not sure the problem since i dont speak the language.
But, I can tell you that you need an extra pair of quotes around the thing for windows that must be omitted on Mac.
reference link - known to work on all versions of windows, plus mac - Although it has survived a few different executables so far, I had some issues executing dos batch files with it.
PS - I plan to update the executeCommand method to separate stdout & stderr when appropriate - thanks for the idea.
