See, HP is open sourcing widgetry very much like theirs, widgetry that it developed for itself over the last seven years at the cost of 'millions of dollars,' it says, and 60 man-years work that sorts out the various licenses that govern open source software - imagine, there are 1,700 licenses in OpenOffice alone - and lets you know if said licenses have been tinkered with in any way. It calls it FOSSology and has made it available at FOSSology.org under the GPLv2. It's designed, it says, to address the acquisition, tracking and licensing of FOSS. It can detect code reuse and provenance even if the code has been changed.
