 The crfc2asn1.pl script can be used to extract ASN.1 data from RFC texts.
 For instance, it is used to extract X.509, MEGACO, and LDAPv3 ASN.1 modules
 from the corresponding RFC texts (rfc3280.txt, rfc3525.txt, rfc4211.txt).

+
+GENERAL INFORMATION
+===================
+
+The 3GPP TS 36.413 version 14.4.0 S1 Application Protocol (S1AP) APER decoder.
+Invoking `make` will compile the ASN.1 specifications from the
+../s1ap-14.4.0.asn1 file.
+
+OBTAINING THE S1AP SPECIFICATION
+================================
+
+To obtain a different version of S1AP ASN.1 specification, you should go to
+	http://www.3gpp.org/ftp/Specs/html-info/36413.htm
+and download any version of S1AP specification you like.
+
+A .ZIP file with a Microsoft Word .DOC files will download shortly.
+
+You should extract the ASN.1 modules from the chapter 9 of that .DOC file.
+Be careful not to copy any preambles, chapter titles and other non-ASN.1 text.
+
+s1ap-dump USAGE
+===============
+
+The s1ap-dump utility may be used to dump the contents of a APER-encoded
+S1AP protocol data unit. Since S1AP specification contains multiple PDUs,
+a PDU must be selected manually using -p <PDU> command line option:
+
+	./s1ap-dump -iaper -p S1AP-PDU message.per
+
+The list of recognized PDUs may be obtained using `-p list`.
+
+The full list of recognized command line options may be obtained with
+
+	> ./s1ap-dump -h
+
