# Ehouarn: added the following feature:
#          create_make_gcm must be called with list of directories
#          which contain header (or modules) which should be scanned
#          by create_make_gcm when checking dependencies.
#          Example:
#          create_make_gcm dyn3d grid
#          means that header/modules will be looked for in directories
#          ., dyn3d and grid
#

# arguments given to create_make_gcm are the directories to scan
