contains:

@table @file

@item url

manually deal with.

@item max
If may contain maximal number of messages per current feed to keep and
process.

@item etag, hdr, out
Those files are used by @command{curl} to keep the content, its proper
@code{mtime} (for @code{If-Modified-Since} header generation),
@code{ETag} and response headers for debugging.

@item feed.zst
It contains the content itself. Compressed with
@url{https://facebook.github.io/zstd/, Zstandard}.

@item download.hash, parse.hash
SHA-512 hash of the @file{feed.zst}, used to determine if feed was
updated and parser has to do the job.

@item title
Automatically generated file with the title of the feed.

@item cur/, new/, tmp/
Directories necessary for making the directory Maildir mailbox. They
contain parsed news posts.

@item encs/, warcs/
