# popy_env

For all the Command Line Tools to work, we must first update the internal paths on your computer and set some environment variables. To do this, we provide a popy_env tool that you run from a command prompt (or Powershell):-

    $ popy_env

If the command is successful, the text in the command prompt should change from white to light blue (if in a dos prompt).

You can achieve the same thing by opening the Open a PoPy Command Prompt from your desktop or the Start Menu - the shortcut starts a new DOS prompt then automatically calls ‘popy_env’.

The settings initialised by popy_env are summarised by the popy_info tool.
