software libre

is the term commonly used on continental Europe, and increasingly in other non-anglophone areas for Free & Open-Source Software/Code.
Anglophones sometimes have arguments over "free" v. "open" (libre, gratis, abierto...); the continentals don't waste their time.
The Spanish sometimes say codigo abierto (open code) too when referring to this concept.
See free software and FOSS.
