 C !INTRODUCTION:  
 C \section{Generica Advection Diffusion Package}  
 C  
 C Package "generic\_advdiff" provides a common set of routines for calculating  
 C advective/diffusive fluxes for tracers (cell centered quantities on a C-grid).  
 C  
 C Many different advection schemes are available: the standard centered  
 C second order, centered fourth order and upwind biased third order schemes  
 C are known as linear methods and require some stable time-stepping method  
 C such as Adams-Bashforth. Alternatives such as flux-limited schemes are  
 C stable in the forward sense and are best combined with the multi-dimensional  
 C method provided in gad\_advection.  
 C  
 C There are two high-level routines:  
 C  \begin{itemize}  
 C  \item{GAD\_CALC\_RHS} calculates all fluxes at time level "n" and is used  
 C  for the standard linear schemes. This must be used in conjuction with  
 C  Adams-Bashforth time-stepping. Diffusive and parameterized fluxes are  
 C  always calculated here.  
 C  \item{GAD\_ADVECTION} calculates just the advective fluxes using the  
 C  non-linear schemes and can not be used in conjuction with Adams-Bashforth  
 C  time-stepping.  
 C  \end{itemize}
