			==Operating with terminfo==
			Dump a database entry with <tt>infocmp</tt>. This produces a source which can be compiled using <tt>tic</tt>. By default, <tt>tic</tt> writes a local database entry. The database structure varies between different environments, and ought not be relied upon. Moving a terminfo database TERM from one machine to another is thus best accomplished by:
			<ol>
			<li>Run <tt>infocmp TERM</tt> on a machine with the database TERM, capturing the output to FILE
			<li>Write the database entry TERM on the remote machine with <tt>tic</tt> FILE
			</ol>
