# $Id$
# Basic plan here is to read in csv files for tabular data (roa
# requests, child asn assignments, child prefix assignments), read
# command line or magic file for my own handle, and read or generate
# pem for bpki ca cert and bpki ee cert (cannot do latter without
# corresponding bpki ee pkcs10). whack all this together and generate
# some xml thing in format to be determined (need to write schema).
import subprocess, csv, xml.etree.ElementTree
# The following should all be configurable on command line, as perhaps
# should the csv conventions (dialect, delimiter, see csv module doc
# for all the fun one can have here). For now, just wire all this in,
# add command line junk later.
