Somebody just pointed me to "sloccount" a program to count the number of lines of code and what it would cost to write:
zef@zef:~/keytopic$ sloccount WEB-INF/src Creating filelist for src Categorizing files. Computing results. SLOC Directory SLOC-by-Language (Sorted) 12659 src java=12659 Totals grouped by language (dominant language first): java: 12659 (100.00%) Total Physical Source Lines of Code (SLOC) = 12,659 Development Effort Estimate, Person-Years (Person-Months) = 2.87 (34.49) (Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05)) Schedule Estimate, Years (Months) = 0.80 (9.60) (Basic COCOMO model, Months = 2.5 * (person-months**0.38)) Estimated Average Number of Developers (Effort/Schedule) = 3.59 Total Estimated Cost to Develop = $ 388,294 (average salary = $56,286/year, overhead = 2.40). SLOCCount is Open Source Software/Free Software, licensed under the FSF GPL. Please credit this data as "generated using 'SLOCCount' by David A. Wheeler."
So we'd just have to sell about 400 copies of KeyTopic to play even ;)
