3. CodeCount Overview
CodeCount is one of the most popular SLOC counting tools publicly available
About 20+ downloads per day
Many CSSE Affiliates use CodeCount as the standard SLOC counting tool
SLOC counting rules are well-defined
Latest Releases are only available to Affiliates members
CodeCount toolset is the only tool that supports counting logical SLOC for many languages (17+)
CodeCount development and maintenance efforts are supported by CSSE Affiliates
