The linux estimate and basis:

Total Physical Source Lines of Code (SLOC)                = 4,287,449
 Development Effort Estimate, Person-Years (Person-Months) = 1,302.68 (15,632)
  (Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05))
 Schedule Estimate, Years (Months)                         = 8.17 (98.10)
  (Basic COCOMO model, Months = 2.5 * (person-months**0.38))
 Estimated Average Number of Developers (Effort/Schedule)  = 159.35
 Total Estimated Cost to Develop                           = $ 175,974,824
  (average salary = $56,286/year, overhead = 2.40). 

EPICS esimate:
EPICS base and extensions
Source code lines							= ~2,000,000   so half
Development effort - Person years                     = ~250         about 20%
Schedule estimate							= ??
Average number of developers                          = ~15          10%
Cost to develop                                       = 22,500,000   We earn more than

                                                                     burdened
