For those unfamiliar, sloccount ("Source Lines of Code Count") counts lines in a language-aware manner (it knows what's in a comment block and what isn't). I think it is kind of the standard for "how many lines of code" and it's been around a long time. It defines line of code as "a physical source line of code (SLOC) is a line ending in a newline or end-of-file marker, and which contains at least one non-whitespace non-comment character". It says (this is just what's in kernel.zip): SLOC Directory SLOC-by-Language (Sorted) 28395 SOURCE ansic=18866,asm=9496,sh=33 0 APPINFO (none) 0 BIN (none) 0 DOC (none) Totals grouped by language (dominant language first): ansic: 18866 (66.44%) asm: 9496 (33.44%) sh: 33 (0.12%) Total Physical Source Lines of Code (SLOC) = 28,395 Development Effort Estimate, Person-Years (Person-Months) = 6.71 (80.56) (Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05)) Schedule Estimate, Years (Months) = 1.10 (13.25) (Basic COCOMO model, Months = 2.5 * (person-months**0.38)) Estimated Average Number of Developers (Effort/Schedule) = 6.08 Total Estimated Cost to Develop = $ 906,871 (average salary = $56,286/year, overhead = 2.40).
