=head1 LEI STORE
-L<lei-init(1)> initializes writable local storage based on
-L<public-inbox-v2-format(5)>.
+lei has writable local storage based on L<public-inbox-v2-format(5)>.
+Commands will automatically initialize the store behind the scenes if
+needed, but you can call L<lei-init(1)> directly if you want to use a
+store location other than the default C<$XDG_DATA_HOME/lei/store>.
+
+The L<lei-import(1)> command provides the primary interface for
+importing messages into the local storage. In addition, other
+commands, such as L<lei-q(1)> and L<lei-blob(1)>, use the local store
+to memoize messages from remotes.
=head2 EXAMPLES
=over
-=item $ lei import mboxrd:t.mbox
+=item $ lei import mboxrd:t.mbox.gz
-Import the messages from an mbox into the local storage.
+Import the messages from a gzipped mboxrd into the local storage.
=item $ lei blob 59ec517f9
that OID isn't found, check if the current git repository has the
blob, trying to reconstruct it from a message if needed.
-=item $ lei blob 59ec517f9 | lei mark - -F eml +kw:flagged +L:next
+=item $ lei blob 59ec517f9 | lei tag -F eml +kw:flagged +L:next
Set the "flagged" keyword and "next" label on the message with the
blob OID of 59ec517f9.
Do the same, but also report unmatched messages that are in the same
thread as a matched message.
-=item $ lei q -t -o mboxcl2:t.mbox --mua=mutt s:lei s:skeleton
+=item $ lei q -t -o /tmp/mdir --mua=mutt s:lei s:skeleton
-Write mboxcl2-formatted results to t.mbox and enter mutt to view the
-file by invoking C<mutt -f %f>.
+Write results to a Maildir at "mdir". Mutt will be invoked
+to open mfolder (C<mutt -f %f>) while results are being fetched
+and written.
=item $ lei q kw:flagged L:next
Search for all flagged messages that also have a "next" label.
-=item $ lei p2q HEAD | lei q --stdin -tt -o mdir
+=item $ lei p2q HEAD | lei q -tt -o /tmp/mdir
Search for messages that have post-image git blob IDs that match those
of the current repository's HEAD commit, writing them to the Maildir
directory "mdir" and flagging the messages that were an exact match.
+=item $ git show -s HEAD | lei lcat
+
+Display a local message for the public-inbox link contained in a
+commit message.
+
+=item $ lei q -f text m:MESSAGE-ID | lei rediff -U5
+
+Feed a message containing a diff to L<lei-rediff(1)> to regenerate its
+diff with five context lines. Unless C<--git-dir> is specified, this
+requires the current working directory to be within the associated
+code repository.

=head1 PERFORMANCE NOTES
-L<Inline::C> is recommended for performance. To enable it, create
-C<~/.cache/public-inbox/inline-c/>.
+L<Inline::C> is required, lei runs as a background daemon to reduce
+startup costs and can provide real-time L<kqueue(2)>/L<inotify(7)>
+Maildir monitoring. L<IO::KQueue> (p5-IO-KQueue on FreeBSD) and
+L<Linux::Inotify2> (liblinux-inotify2-perl and perl-Linux-Inotify2 in
+.deb and .rpm-based distros, respectively) are recommended.
-If Socket::MsgHdr is installed (libsocket-msghdr-perl in Debian), the
-first invocation of lei starts a daemon, reducing the startup cost of
-for future invocations (which is particularly important for Bash
-completion).
+L<Socket::MsgHdr> is optional (libsocket-msghdr-perl in Debian),
+and further improves startup performance. Its effect is most felt
+when using shell completion.
=head1 BASH COMPLETION
shells, as well as improvements to the existing Bash completion, are
welcome.
+=head1 UPGRADING
+
+Since lei runs as a daemon, L<lei-daemon-kill(1)> is required to kill
+the daemon so it can load new code. It will be restarted with the
+next invocation of any lei command.
+
+=head1 CAVEATS
+
+IMAP and NNTP client performance is poor on high-latency connections.
+It will hopefully be fixed in 2022.
