+=head1 NAME
+
+lei - local email interface for public-inbox
+
+=head1 SYNOPSIS
+
+lei COMMAND
+
+=head1 DESCRIPTION
+
+Unlike the C10K-oriented L<public-inbox-daemon(8)>, lei is designed
+exclusively to handle trusted local clients with read/write access to
+the file system, using as many system resources as the local user has
+access to.  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).
+
+Available in public-inbox 1.7.0+.
+
