#Individuals may want to edit the OPT* variables below.
#From the READ.ME:
#You may need to "hand-tune" compiler or optimization options,
#which may be specified by setting the OPT and OPT2 environment
#variables. OPT2 is used to compile only the most performance-critical
#modules and usually will select a very high level of optimization.
#It should be safe to select an optimization which means "treat all
#function arguments as restricted pointers which are not aliased to
#any other object". OPT is used for less preformance-critical modules
#and may be set to a lower level of optimization than OPT2.
