Helper App: Pkg Installer

Newt's Cape recognizes and installs packages from the internet (via NIE):

1. it recognizes a package as a file that ends with .pkg and has one of these MIME type/subtypes:
   • application/x-newton-compatible-pkg (preferred)
   • text/plain
   • */*
   • contains "newton" and ends with "-pkg"
2. it confirms whether to install the package immediately, or add to Inbox for later installation

This helperApp example shows how to change this process in either or both ways:

1. since a server may supply a different MIME type, you would see the error message: Receive Failure [MIMEtype/subtype] unknown helper app; you can register this MIME type with Newt's Cape for further package transfers (until this is de-installed or you reboot). Note: if the package MIME type begins with "text/", you'll need to use Newt's Cape 1.4 to force a binary transfer -- otherwise, it removes/replaces LF characters which would corrupt the package.
