+*fftw-2.1.3-r1.ebuild (13 Feb 2003)
+
+  13 Feb 2003; Nick Hadaway <raker@gentoo.org> fftw-2.1.3-r1.ebuild,
+  files/digest-fftw-2.1.3 :
+  New ebuild which creates links to the standard fftw include/lib names.
+  If you specify SINGLE=yes on the emerge commandline the links will
+  be created to the single precision libs/includes, otherwise by default
+  to the double precision libs/includes.
 
   06 Dec 2002; Rodney Rees <manson@gentoo.org> : changed sparc ~sparc keywords
