+=head1 NAME
+
+lei - local email interface
+
+=head1 SYNOPSIS
+
+lei [OPTIONS] COMMAND
+
+=head1 DESCRIPTION
+
+lei is a command-line tool for importing and searching email,
+regardless of whether it is from a personal mailbox or a public-inbox.
+lei supports a local, writable store built on top of
+L<public-inbox-v2-format(5)> and L<public-inbox-extindex(1)>.
+L<lei-q(1)> provides an interface for querying messages across the lei
+store and read-only local and remote "externals" (inboxes and external
+indices).
+
+Warning: lei is still in its early stages and may destroy mail.
+Be sure to have backups of destinations lei writes to.
+
+Available in public-inbox 1.7.0+.
+
