<code>gc-database</code> allows the server administrator to reorganize
an existing <meta-html> database on the fly.

Invoking <code>gc-database</code> without arguments reorganizes the
session database information, thus reducing the amount of disk space
that it uses.  This program should be run periodically, depending on
your site and usage.

Without an argument, <code>gc-database</code> tries to reorganize the
file <code>/tmp/sessions.db</code>.  Given a database filename, it
reorganizes that database instead.

<meta-html> databases only need reorganizing when many additions and
deletions are made.  For databases containing mostly static data, such
as an address book, or product catalog, reorganization is unnecessary.
