# This is asn2quickder, an ASN.1 compiler with Quick DER backend
#
# Quick DER is a small and efficient library for DER parsing, possible
# entirely without memory allocation in the routines.  This makes it
# perfect for many embedded uses, and the occasional quick actions on ASN.1
# encoded in DER, such as plucking fields out of a certificate or ticket.
#
# This basically is a Python script that invokes a few library routines.
# These install into $(DESTDIR)$(PREFIX)/lib/asn2quickder/asn1ate
# where the reason for the asn2quickder prefix is to avoid naming conflicts
# with any "real" asn1ate intallation; asn2quickder is a branch off asn1ate.
