Compile advanced options

[Hifive]

What is the reason developer wants to "Install BAS engine ....Saves space..."
... what is the purpose of doing this?

I find that the folder size will be increased by about 400mb ... so how can it 'saves space'?

@Hifive Saves space when installing several different scripts.

@hifive You can try to compile with and without that option.
Difference is about 153 mb and all that space takes engines folder.
