# !MODULE: Makefile (in the KPP subdirectory)
#
# !DESCRIPTION: This is main "router" makefile for the KPP solver.  It 
#  compiles the KPP code for one of the following types of GEOS-Chem
#  simulations:
#
#  \begin{enumerate}
#  \item GEOS-Chem "standard" simulation (43 tracers)
#  \item GEOS-Chem "secondary organic aerosol" simulation (54 tracers)
#  \end{enumerate}
#
# The KPP code will be compiled using one of the following numerical solvers:
#
#  \begin{enumerate}
#  \item rosenbrock (This is the default option.)
#  \item lsodes
#  \item radau5
#  \item runge\_kutta
#  \end{enumerate}
#  
# !REMARKS:
# To build the programs, call "make" with the following syntax:
#                                                                             .
#   make TARGET [ OPTIONAL-FLAGS ]
#                                                                             .
# To display a complete list of options, type "make help".
#                                                                             .
# %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
# %%% NOTE: Normally you will not have to call this Makefile directly,     %%%
# %%% it will be called automatically from the main GEOS-Chem Makefile in  %%%
# %%% GeosCore directory!                                                  %%%

#                                                                             .
# Makefile uses the following variables:
#                                                                             .
# Variable   Description
# --------   -----------
# SHELL      Specifies the shell for "make" to use (usually SHELL=/bin/sh)
# ROOTDIR    Specifies the root-level directory of the GEOS-Chem code
# DOC        Specifies the directory where GEOS-Chem documentation is found
# HDR        Specifies the directory where GEOS-Chem include files are found
# LIB        Specifies the directory where library files (*.a) are stored
# MOD        Specifies the directory where module files (*.mod) are stored
# AR         Sys var w/ name of library creator program (i.e., "ar", "ranlib")
# MAKE       Sys var w/ name of Make command (i.e, "make" or "gmake")
# NTRAC      Cmd line argument; specifies either 43 or 54 tracer simulation
# KPPSOLVER  Cmd line argument; specifies the type of integrator to use
#
# !REVISION HISTORY:
