Why is there variables.less in the bootstrap 3 sources, but not style.less?

Question

Source

I downloaded the sources of bootsrtap 3, where, as I understand it, there should be variables.less and style.less in the less folder, but in fact, of the two of them, there are only variables.less. Please tell me why this is so, or just throw off the contents of this file.
ps downloaded from here https://github.com/twbs/bootstrap/archive/v3.1.0.zip

Answer 1

Most likely instead of style.less -> bootstrap.less, because variables.less and other files will be imported into it
