qtmaildir is a Qt6 desktop client for reading and organizing a local
Maildir that notmuch has indexed. It is a GUI counterpart to neomutt for
the parts of mail handling that are easier with a mouse and a real HTML
renderer.

It does no network protocol work at all: there is no POP, IMAP or SMTP,
and no sync implementation. Mail arrives in your Maildir by whatever you
already use (mbsync, offlineimap, fetchmail) and is indexed by
'notmuch new'. Fetching is delegated to a command you configure, so it
joins the lock that already serializes your script against cron rather
than running a second mbsync over the same Maildir. Sending is not
implemented.

You need a working notmuch database before qtmaildir is useful; it does
not create or configure one. The Maildir path is deliberately not
configurable, since notmuch already stores it as database.path.

Qt6 (including WebEngine), gmime and cmake are part of Slackware, so
notmuch is the only dependency that is not.

Configuration lives at ~/.config/qtmaildir/qtmaildir.conf and is
documented in /usr/doc/qtmaildir-$VERSION/README.md.

This package is built with the test suite disabled
(-DQTMAILDIR_BUILD_TESTS=OFF), which skips the Qt6::Test dependency and
builds nothing that would ship. Note that this option was added after
0.4.0 was tagged: with the 0.4.0 tarball the flag is accepted but has no
effect, so that build still compiles the tests and needs Qt6::Test.
