Compression level and command-line

[MathieuPinard]

I'm currently automating build creation using MIABUILD, which is very convenient. I know the compression level can be adjusted using a slider inside the Project Options dialog.

Would it be possible to have the compression level changed based on a command-line parameter passed to MIABUILD?

I'd like to have my automated nightly build compressed with the highest compression setting, but during the day I'd like that setting to be less strong in order to have my day builds completed faster.
