Terminology: There is some Google-internal terminology used in some of these documents, which we clarify here for external readers: CL: Stands for “changelist,” which means one self-contained change that has been submitted to version control or which is undergoing code review. Other organizations often call this a “change” or a “patch.” LGTM: Means “Looks Good to Me.” It is what a code reviewer says when approving a CL. quote from: https://google.github.io/eng-practices/#terminology https://google.github.io/eng-practices/#terminology
