WarpIN allows you to use environment variables from script tags which support macro substitution.

A number of environment variables are guaranteed to be defined while a script is being processed by WarpIN. These are called "script variables".

In addition, since WarpIN prompts the user if a variable is referenced, but has currently no value, as an archive creator, you can also force WarpIN to prompt the user for additional information. See the VARPROMPT tag for details. The following pages list the environment variables which WarpIN will recognize. All those variable names start with WARPIN_.
