• Show usage (short) help if command line parameter is wrong #5780 We should show the full/short command line help in Bash style if a parameter is wrong.
• Reformat command line help for powershell -Help #4989 We should reformat the help in Bash style:
  • sort parameter list in alphabetical order.
  • replace long header on powershell[.exe] [options]
• Reformat command line help for powershell -Help #4989 We should add more examples in line of the help.
