"""
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 certificate and BPKI EE certificate (cannot do latter
without corresponding BPKI EE PKCS #10). Whack all this together and
generate some XML thing (format still in flux, see schema).
