A less error occured trying to build your bundle.

[gedex]

Boots always generate /css/error.txt with following content:

A less error occured trying to build your bundle. You've likely entered an invalid input into the less variable field. Check your syntax and try again!

thanks!

{"type":"Parse","message":"Syntax Error on line 792","index":25106,"filename":"bootstrap.css","line":792,"column":11,"extract":[" *margin: -5px 0 5px;"," ove rflow: hidden;"," background-color: @top;"]}

Even with your example:

boots --js bootstrap-modal.js,bootstrap-tooltip.js --css modals.less,tooltip.less -o public/bootstrap

is this expected behavior? or did I do something wrong?

Looks like there's a bug with the Bootstrap customize tool. I've reported it here: https://github.com/twitter/bootstrap/issues/6288
