GENERAL INFORMATION
===================
The SAE J2735-201603 Dedicated Short Range Communications (DSRC)
Message Set Dictionary decoder.
Invoking `make` will compile the ASN.1 specifications from the
../j2735.asn1 file.
THERE IS NO j2735.asn1 FILE THERE YET!
OBTAINING THE J2735 SPECIFICATION
=================================
Go to http://standards.sae.org/j2735_201603/ and download the files.
You should extract the ASN.1 module from there and save it
as the ../j2735.asn1 file. The ../j2735.asn1 file should start with
the following line
"DSRC DEFINITIONS AUTOMATIC TAGS ::="
and end with the "END" token.
Be careful not to copy any non-ASN.1 preambles from that .DOC file.
After obtaining the j2735.asn1, type `make` in the directory containing
this README file.
j2735-dump USAGE
================
The j2735-dump utility may be used to dump the contents of the UPER-encoded
DSRC message record file:
./j2735-dump j2735file.per # Print as XML (BASIC-XER)
The full list of recognized command line options may be obtained with
> ./j2735-dump -h
