cloc 1.92 Count source lines of code (SLOC) and other source code metrics
cloc counts blank lines, comment lines, and physical lines of source code in many programming languages. Given two versions of a code base, cloc can compute differences in blank, comment, and source lines.
cloc contains code from David Wheeler's SLOCCount. Compared to SLOCCount, cloc can handle a greater variety of programming languages.
