... it is estimated it would have costed about 90 person years to develop :)
At least that's what the program sloccount claims. This is obviously not
scientific calculation, just for fun. The program is primarily meant to
calculate the effective source lines of code (sloc) in a project. I have
ran it on GnuCash, here's the full summary for those interested:
Totals grouped by language (dominant language first):
ansic: 260622 (77.04%)
lisp: 42674 (12.61%)
sh: 16955 (5.01%)
python: 6823 (2.02%)
cpp: 6387 (1.89%)
perl: 4835 (1.43%)
Total Physical Source Lines of Code (SLOC) = 338,296
Development Effort Estimate, Person-Years (Person-Months) = 90.53 (1,086.36)
(Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05))
Schedule Estimate, Years (Months) = 2.97 (35.61)
(Basic COCOMO model, Months = 2.5 * (person-months**0.38))
Estimated Average Number of Developers (Effort/Schedule) = 30.50
Total Estimated Cost to Develop = $ 12,229,349
(average salary = $56,286/year, overhead = 2.40).
