Anything you add here will be appended at the end of the [Config] section during Compile.
[Files]
Anything you add here will be appended at the end of the [Files] section during Compile.

[Alias]

[Other]
This "catch-all" option allows you to add other sections if you want. Anything you add here will be appended at the end of the Project file during Compile.
