-Command line utilities for AMR-EFR hybrid
-=========================================
-
-The present package includes a small set of command line utilities that work
-with the AMR-EFR hybrid described above:
-
-amrefr-encode-r
-amrefr-decode-r
-
-	These two utilities function just like gsmefr-encode-r and
-	gsmefr-decode-r described in Codec-utils article, but implement the
-	AMR-EFR hybrid version of the codec instead of original EFR.  The
-	no-DTX limitation applies: amrefr-encode-r lacks -d option, and the
-	input to amrefr-decode-r must not contain any SID frames.
-
-amrefr-tseq-enc
-amrefr-tseq-dec
-
-	These two utilities are AMR-EFR counterparts to gsmefr-etsi-enc and
-	gsmefr-etsi-dec test programs described in EFR-testing article.  They
-	pass all tests on the non-DTX t??_efr.* sequences in ETSI's
-	amr122_efr.zip, but not on any of the DTX sequences included in the
-	same ZIP.  Just like amrefr-encode-r, amrefr-tseq-enc lacks -d option,
-	and amrefr-tseq-dec rejects input containing SID frames.
