1	!
2	! This module is the entry point from WRF ARW to the wildland
3	! fire module. The call to sfire_driver advances the fire module by
4	! one timestep. The fire module inputs the wind and outputs
5	! temperature and humidity tendencies. The fire module also inputs a
6	! number of constant arrays (fuel data, topography). Additional
7	! arguments are model state (for data assimilation) and constant arrays
8	! the model gives to WRF for safekeeping because it is not allowed
9	! to save anything.
10	!
11	! Contributions to this wildland fire module have come from individuals at
12	! NCAR, the U.S.D.A. Forest Service, the Australian Bureau of Meteorology,
13	! and the University of Colorado at Denver.
