+
+BEWARE OF THIS SOX BINARY - IT MIGHT HAVE BEEN COMPILED INCORRECTLY.
+
+I replaced Gradint's previous PPC-only sox binary with this dual i386/PPC
+version because Mac OS 10.7 dropped Rosetta.  However, sox's Makefile didn't
+support dual architecture, so I wrote my own gcc commands to do it.  There
+were lots of warnings, especially about GSM.  I wasn't worried about that
+because Gradint doesn't use that functionality.  But be careful about using
+this SOX binary elsewhere, especially for GSM-related processing.
+
+This version of sox does NOT run on OS X 10.8 (it complains about missing
+libltdl.7.dylib).  Use sox-14.4.2 instead for that.
