Create feeds state directories under feeds/. You can do it manually:
$ mkdir -p feeds/my_first_feed/{cur,new,tmp}
$ echo http://example.com/feed.atom >feeds/my_first_feed/url
Or you can convert Newsboat urls file (containing many lines with
URLs) with urls2feeds to subdirectories hierarchy:
$ ./urls2feeds <~/.newsboat/urls $ cat feeds/blog.stargrave.org_russian_feed.atom/url http://blog.stargrave.org/russian/feed.atom
urls2feeds won’t touch already existing directories and will
warn if any of them disappears from urls.
