AbleCommerce Shopping Cart Software

I'm working on a custom theme and looking at customizing the bootstrap responsive theme. I see mention of various LESS files but the only LESS file in the zip download of the WAP is style.less. Within that file I see several @import statements and other less files, e.g., /less/buttons.less. But where are these less files located? I must be missing something here.

Found the answer - essentially these files need to be downloaded, along with a less compiler, etc.
