# This Makefile.am specifies a set of codelets, efficient transforms
2
# of small sizes, that are used as building blocks (kernels) by FFTW
3
# to build up large transforms, as well as the options for generating
6
# You can customize FFTW for special needs, e.g. to handle certain
7
# sizes more efficiently, by adding new codelets to the lists of those
8
# included by default. If you change the list of codelets, any new
9
# ones you added will be automatically generated when you run the
10
# bootstrap script (see "Generating your own code" in the FFTW
