HOWTO

# FFTW
# ====
# Below I include the latest 2.x and 3.x versions.  Stick with 3.x unless
# you have an application that neeeds 2.x (like MythTV, for example).

# Because binaries, includes, and libraries are all named differently, you
# can install a 2.x and 3.x version at the same time.

# Uninstall instructions for both are at the bottom.  If you're going from
# one source-installed version to another, you may want to uninstall the
# old one first to make sure there aren't old files lying around.

# fftw 2.1.5
