XPA Packaging Format

An XPP bundle directory can be packaged into an XPA archive for distribution. Users install the XPA to restore it back into an XPP bundle.

XPA is essentially a .zip file with a very simple structure:

Demo.xpa (zipped)
    - Payload
        - A-Script-Bundle.xpp

Place your prepared .xpp bundle inside an empty directory named Payload, zip the Payload directory, and rename the zip file extension to .xpa.
