# This script makes use of the fact that the hfs+ file system does funny
# things with case:     
#    
#    If you have a file named  a.F90, you can not have another file
#    named a.f90.  BUT--- you can use a.f90 or a.F90 interchangeably
#    in most cases:
#     
#         ls a.F90     and     ls a.f90  should give the same information.
#         diff a.F90 b.F90    and   diff a.f90 b.F90  should give the same result
#
#     Now for the problem:  The NAG compiler will not compile   a.F90, but it
#     will compile a.f90.  But when compiling a.f90, it will not automatically
#     invoke fpp.
#
#     NAG's rules state that a.F90 SHOULD compile with fpp.  So our solution is:
#
#       1.  If the argument is a.f90, just leave it alone.
#       2.  If an argument is a.F90, change it to a.f90 and turn on the -fpp flag.
#
#     Note that this is done with sed on each argument, so if any of the arguments is
#     .F90, then -fpp will be turned on:
#


FPP=''
args=''
for arg in $*
do
 case $arg in
  *\.F) FPP='-fpp'; arg2=`echo $arg | sed -e 's/F$/f/'`; args="$args $arg2";;
  *\.F90) FPP='-fpp' ; arg2=`echo $arg | sed -e 's/F90$/f90/'` ; args="$args $arg2";;
  *\.F95) FPP='-fpp' ; arg2=`echo $arg | sed -e 's/F95$/f95/'` ; args="$args $arg2";;
  *) args="$args $arg";;
