 Description: Provides an R implementation of the Vegetation
-    Photosynthesis and Respiration Model (VPRM) and tools to estimate
-    VPRM parameter values from observations.  VPRM is a simple
-    diagnostic land surface model based on light-use efficiency.  VPRM
-    diagnoses gross ecosystem exchange (GEE) of carbon dioxide,
-    ecosystem respiration (R), and net ecosystem exchange (NEE) of
-    carbon dioxide. To cite the VPRMLandSfcModel R package or the VPRM
-    model itself in a publication, or for a more detailed description
-    of VPRM, see (within R) 'citation("VPRMLandSurfaceModel")'.

 # Description:
 
-Provides an R implementation of the Vegetation Photosynthesis and
-Respiration Model (VPRM) of Mahadevan et al (2008) and tools to
-estimate VPRM parameter values from observations.  VPRM is a
-simple diagnostic land surface model based on light-use
-efficiency.  VPRM diagnoses gross ecosystem exchange (GEE) of
-carbon dioxide, ecosystem respiration (R), and net ecosystem
-exchange (NEE) of carbon dioxide.  VPRM parameters may be
-estimated separately for different subsets of a dataset of
-observations.  If the Rmpi package is installed, such separate
-parameter estimations may be run in parallel.
