Hi, I was trying to use the Apache ASN.1 tool to work on asn ASN.1 grammar which I am having. However I was running into some issues in trying to understand how to generate the Java files which will be compatible with my ASN.1 grammar. I was trying to search for some documentation on the same, but without success. Could you please give any information on how I could accomplish the compilation of my ASN.1 grammar or if there is any documentation which lists the procedures for doing it.
