for the hell of it I ran generic sloccount on various versions of grass.
http://www.dwheeler.com/sloccount/
Useless, but interesting.
Highlights:
GRASS 5.0.3:
Total Physical Source Lines of Code (SLOC) = 772,827
Development Effort Estimate, Person-Years (Person-Months) = 215.53 (2,586.41)
Total Estimated Cost to Develop = $ 29,115,753
GRASS 5.3.0:
Total Physical Source Lines of Code (SLOC) = 918,816
Development Effort Estimate, Person-Years (Person-Months) = 258.48 (3,101.71)
Total Estimated Cost to Develop = $ 34,916,572
GRASS 5.7.0:
Total Physical Source Lines of Code (SLOC) = 333,939
Development Effort Estimate, Person-Years (Person-Months) = 89.31 (1,071.67)
Total Estimated Cost to Develop = $ 12,064,022
Linux Kernel 2.4.27:
Total Physical Source Lines of Code (SLOC) = 3,511,066
Development Effort Estimate, Person-Years (Person-Months) = 1,056.19 (12,674.25)
Total Estimated Cost to Develop = $ 142,676,539
Debian 2.2 (Potato) [some time in 2001]:
Total Physical Source Lines of Code (SLOC) = 55,201,526
Development Effort Estimate, Person-Years (Person-Months) = 14,005.78 (168,069.41)
Total Estimated Cost to Develop = $1.9 billion
