# Usage of the script makeioipsl_fcm
#
# makeioipsl_fcm compiles IOIPSL using the Fcm software developed
# by the Hadley Centre. Fcm is stored in tools directory. 
# Platform specific compile options are found in the arch directory. 
########################################################################

Usage:

./makeioipsl_fcm -arch XXX [Options] 


Mandatory argument:

-arch XXX  : name of the archicture file containg platform dependent compile options. 
             The files arch/arch-XXX.fcm and arch/arch-XXX.path must exist. If the 
             file arch/arch-XXX.env exist, it'll be sourced before compilation starts.

Main options:
[-h]             : show this help
[ -full ]        : activate full recompiling 
[ -arch_path XXX ] : directory of the archicture file containg platform dependent compile options. 
                     Default is ./arch directory. If the files are not found in the folder given by arch_path, 
                     the default ./arch folder will be used. 

Options for optimization, choose only one of the following
[ -prod ]        : compilation for production (all optimization)
[ -dev ]         : compilation for development (low optimization and -g)
[ -debug ]       : compilation for debugging (no optmization and all debug options)

[ -job x ]       : activate parallel compiling on x task, default is 1 task
