# We start by tangling all the org-mode files.

# Then we create the list of ~*.o~ files to be created, for library
# functions:


OBJECTS="qmckl_f.o"
for i in $(ls qmckl_*.c qmckl_*f.f90) ; do
    FILE=${i%.*}
    OBJECTS+=" ${FILE}.o"

TESTS=""
for i in $(ls test_qmckl_*.c) ; do
    FILE=${i%.c}
    TESTS+=" ${FILE}.o"

# and for tests in Fortran:


TESTS_F=""
