FOSS: software heaven, licenses nightmare !

So you feel like you have found a goldmine but at the same time that you have entered a nebulous world of licenses?

Well, you are not alone.

This is why HP came up w/ "FOSSology" – “The study of FOSS.” As development progressed, we quickly realized that the analysis of open source licensing was only one application of what was quickly becoming a valuable general-purpose software data mining framework.

This should help you in your quest to assess the quality of the "jewl" you uncovered, including any legal constraints for your company and/or project.
