Similar to the concept of variable substitution, EachScape provides certain values that are available to your app. You can't modify these values, however, only reference their values.
This is version [[sys:version]] of my cool app.
Will replace the string [[sys:version]] with the complete version and build number. Depending on that value, the result might look something like this:
This is version 1.1.14 of my cool app.
