+soxdial - generate DTMF (touchtone, dialtone, or blue box) audio
+
+soxdial uses sox to generate DTMF tones (aka touchtone dialling),
+dialtone, and/or "blue box" tones. Output can be played through the
+system sound card, or saved to a file of any type supported by sox.
+
+soxdial is a perl script that doesn't require any external
+dependencies other than perl and the sox binary in $PATH.
+
+For full documentation, run "soxdial --help".
