.SYNOPSIS
  warpbox: command line uploader for Warpbox
.DESCRIPTION
  Set the server once, then upload anything:
    setx WARPBOX_HOST "https://your.warpbox.host"
    warpbox .\report.pdf

  Install (PowerShell):
    iwr "$env:WARPBOX_HOST/static/api/warpbox.ps1" -OutFile $HOME\warpbox.ps1
    # add a function to your $PROFILE:  function warpbox { & "$HOME\warpbox.ps1" @args }

  Auth: set the token once so it never lands in your command history.
    setx WARPBOX_TOKEN "wbx_your_token"
  Create a token under Account, Access tokens.

.EXAMPLE
  .\warpbox.ps1 .\report.pdf

  .\warpbox.ps1 -Password 123 -Expiry 2d .\photo.png .\clip.mp4
