Any chance you've got the css file that is generated by this based on the default bootstrap values?

Apologies, I had no notification you had commented.

I've made a few changes to this, after realising it needs to override the border-radius mixins from Bootstrap, to explicitly set border-radius to 0 if $enable-rounded == false.

I've compiled the css, but this is based on $enable-rounded being false (so no border-radius). If you want rounded corners, either compile the scss yourself or modify thr border-radius properties to match what you want.

Anyway, the css file is here:
