<P><FONT SIZE="+1"><B><I>PURPOSE</I></B></FONT></P>
<P>The <B>zmore</B> command is the GNU version of the venerable UNIX <B>more</B> command. <B>Zmore</B> prints files to the screen, one screen at a time. The twist here is that <B>zmore</B> will display files compressed with <B>gzip</B>. There are no command-line options to <B>zmore</B>, only commands that can be invoked when <B>zmore</B> is running.</P>

<P><B>answer</B> <I>option(s)</I></P>
<P><FONT SIZE="+1"><B><I>PURPOSE</I></B></FONT></P>
<P>The <B>answer</B> command is a secretarial tool used to transcribe telephone messages to an electronic mail message in <B>elm</B>. After launching, <B>answer</B> checks the <B>.elm/aliases</B> file for a list of users and then guides the user through a form designed to mimic phone-message slips (with fields like “Message-To:” and “Please Call”).</P>

<P><B>audiocompose</B> <I>filename</I></P>
<P><FONT SIZE="+1"><B><I>PURPOSE</I></B></FONT></P>
<P>The <B>audiocompose</B> command records audio. If you want to record audio clips to attach to your outgoing mail messages, this is the command to use. Run this command on the command line with a filename; you’ll be prompted to record a file, and then asked if you want to listen to the file after recording it.</P>
<P>Then, you’ll need to use the <B>audiosend</B>, <B>mailto</B>, or <B>metamail</B> command to attach the file to an outgoing mail message.</P>

<P><FONT SIZE="+1"><B><I>PURPOSE</I></B></FONT></P>
<P>The <B>audiosend</B> command, unlike <B>audiocompose</B>, can be used to both record the audio and e-mail it to another user. The audio segment makes up the entire e-mail message; you can’t attach text or other files to the mail message.</P>
<P>The command is simple: You use <B>audiosend</B> on a command line, along with an e-mail address. (If you don’t specify an address, the command will prompt you for one.) The command then prompts you for <I>Subject</I> and <I>Cc</I> fields, after which you record your message. Before sending the message, <B>audiosend</B> asks if you want to rerecord the message or listen to it.</P>

<P>The <B>biff</B> command notifies you that new mail has been received, as long as your system uses <B>sendmail</B> or <B>smail</B> as a mail-transport agent. To see the current status of <B>biff</B>, type it alone on a command line. To enable <B>biff</B>, use the <B>y</B> option; to disable <B>biff</B>, use the <B>n</B> option.</P>
