# Makefile for ESMA components.
#
# REVISION HISTORY:
#
# 20oct2004  da Silva  First ESMA version.
# 23Aug2006  da Silva  Driver for making either MAPL or GEOS_Base.
# 26Aug2008  Stassi    No longer builds GEOS_Base; merged with MAPL_base.mk
# 27Oct2008  da SIlva  Some clean up for ESMF v3
# 09Feb2010  Todling   Another stub-lib was added (stub2). Saidly, it cannot be 
#                      folded w/ the exiting stub-lib
# 17Jul2012  Trayanov  Removed stub2
# 16Aug2012  Purnendu  Added subdir TeX
