1 * test: item_order_ascending.sh -> sample_asc.sh
2 * Make directories/items read-only.
3 * no date -> current date. write all items with date >=
5 * check whether dates are handled properly (timezones!)
6 * fix remaining bugs (see README)
7 * support lastBuildDate and pubDate for channels
8 * replace assertions by proper error handling
9 * clean state after a tag level is left, so we can pipe
10 multiple streams, one after another, into one instance.
