=head1 NAME

public-inbox-compact - compact Xapian DBs in an inbox

=head1 SYNOPSIS

public-inbox-compact INBOX_DIR

public-inbox-compact --all

=head1 DESCRIPTION

public-inbox-compact is a wrapper for L<xapian-compact(1)>
which locks the inbox and prevents other processes such as
L<public-inbox-watch(1)> or L<public-inbox-mda(1)> from
writing while it operates.

It enforces the use of the C<--no-renumber> option of
L<xapian-compact(1)> which is required to work with the
rest of the public-inbox search code.

This command is rarely needed for active inboxes.

Using the C<--compact> option of L<public-inbox-index(1)>
is recommended, instead, and only when doing a C<--reindex>.

=head1 OPTIONS
