=head1 NAME

public-inbox-xcpdb - copy Xapian DBs (for format upgrades)

=head1 SYNOPSIS

	public-inbox-xcpdb INBOX_DIR

=head1 DESCRIPTION

public-inbox-xcpdb is a wrapper for L<copydatabase(1)> for
upgrading to the latest database format supported by Xapian
(e.g. "glass" or "honey").

It locks the inbox and prevents other processes such as
L<public-inbox-watch(1)> and L<public-inbox-mda(1)> from
writing while it operates.

This is intended for upgrading the database format used by
Xapian.  It DOES NOT upgrade the schema used by the
public-inbox search interface (see L<public-inbox-index(1)>).
