Such copyright can be determined on a case-by-case basis by examining the author of each portion of a file in the revision-control commit records of the project, or by consulting representative comments claiming copyright ownership for a file. For example, the text: "Copyright (c) 2011 Google Inc." appears in some files, and these files thereby denote that their author and copyright-holder is Google Inc. In all such cases, the absence of explicit licensing text indicates that the contributor chose to license their work for distribution under identical terms to those Mozilla has chosen for the collective work, enumerated at the top of this file. The only difference is the retention of copyright itself, held by the contributor.
