+zita-convolver (audio convolution engine)
+
+No dependencies, but there are some build options:
+
+SSE - Use or don't use SSE for floating point math. Default is "auto",
+which checks the build host CPU for SSE support. You can override this
+with SSE=yes or SSE=no if you're going to install the package on a
+different host from the build host (or maybe if you know for a fact,
+due to benchmarking, that your CPU's SSE implementation is slow or buggy).
+
+MMX - Use or don't use MMX. Default is "auto". Set MMX=yes or MMX=no
+to override.
+
+FORCE_O2 - Normally, Slackware packages are built with the optimization
+set to -O2. This package defaults to -O3 (because that's what upstream
+uses), but if you *really* want, you can set FORCE_O2=yes. I can't think
+of a good reason to do this, you probably can't either :)
+
+With no options, the default is to build a package optimized for the
+build host (which is just what you want, if you're going to build and
+install on the same machine).

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
