It is worded wrong. It is not about different file formats to load, but 
about loading different RFC1035 master file format zone files. Some 
containing correct zones and some containing deliberate errors (like 
impossible TTLs or bogus RDATA of wrong format, et cetera).

I believe the goal is to make a collection of many zone files and a way 
to use them for testing.

BIND 9 source contains many zone files. I think they are all named 
"*.db" under bin/tests/. Maybe these can give some ideas and maybe some 
or all can be re-used. You can also collect and create your own zone 
data. Consider to document somewhere (maybe the files themselves) what 
they contain and expected behaviour.

Also need some way to test using those master files. I think Cucumber 
will be used in the long run. But for now, maybe some simple shell or 
python scripts to load the files and check the results: verbose output 
(see task 89), store and compare sqlite text dumps, or maybe even real 
queries.

I am guessing that "name cleanup" is to report what was derived for the 
origin (in the case that the origin is not defined on the command line).

We talked about various different "verbose" options for b10-loadzone, 
but for now:

- report to STDERR

- report origin name

- show count of how many RRsets or records were loaded

- report where the data is stored to (for now is a sqlite database file)

- if possible, report whether or not a new database is created or an 
  existing one is updated

- maybe report whether a new zone was created or an existing zone was 
  replaced

- maybe periodically show a count of how many RRSets or records have 
  been loaded

"%done" is for periodically showing the percentage of the master file 
data that is loaded until complete. I am not sure how relevant or easy 
that is to do now as I don't know if it pre-parses the loaded data to 
get something to compare with. It is probably not required in the first 
"verbose" option.
