+pcm-sms-decode	Some TI-based vendor firmwares (not TI's original and not
+		FreeCalypso) implement SMS storage in their FFS in a file named
+		/pcm/SMS in the same format in which SMS records are stored in
+		SIM cards (EF_SMS elementary file).  Pirelli's firmware is one
+		major user of this mechanism.  This /pcm/SMS file can be read
+		out in vivo via fc-fsio or extracted in vitro via tiffs; the
+		new pcm-sms-decode utility decodes the stored SMS content from
+		this binary file similarly to sms-pdu-decode.
