<ptext>
The following utilities are delivered with most <meta-html> products:

<h3> Image Utilities </h3>
<ul>
  <li> <a href="imagemap.mhtml"><b>imagemap</b></a>:
  A program which handles the server-side interpretation of clickable
  images.
</ul>

<h3> Database Utilities </h3>
<ul>
  <li> <a href="dbdump.mhtml"><b>dbdump</b></a>:
  A program which prints out the contents of a <meta-html> database in
  human-readable form.

  <li> <a href="dbpack.mhtml"><b>dbpack</b></a>:
  A program which converts a <meta-html> database from a binary format
  to an ASCII representation, or from an ACSII representation to a
  binary format.

  <li> <a href="dbcreate.mhtml"><b>dbcreate</b></a>:
  A program which creates a <meta-html> packed database from an ASCII
  text file containing comma-separated fields.  This program uses a
  <i>description file</i> to control the way in which the text file is
  interpreted, and of the created database.
</ul>

<h3> Session Utilities </h3>
<ul>
  <li> <a href="list-sessions.mhtml"><b>list-sessions</b></a>:
  A program which displays the existing sessions in the session database.

  <li> <a href="delete-session.mhtml"><b>delete-session</b></a>:
  A program which allows you to manually delete an active session.

  <li> <a href="set-session-timeout.mhtml"><b>set-session-timeout</b></a>:
  A program which allows you to manually set the timeout for a
  particular session directly from the command line.

  <li> <a href="get-session-var.mhtml"><b>get-session-var</b></a>:
  A program which returns the value of a variable for a specific session.

  <li> <a href="set-session-var.mhtml"><b>set-session-var</b></a>:
  A program which set the value of a variable for a specific session.

  <li> <a href="gc-database.mhtml"><b>gc-database</b></a>:
  A program which 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.

  <li> <a href="reap-sessions.mhtml"><b>reap-sessions</b></a>:
  A program which immediately removes sessions which have timed out
  from the session database.  This program is rarely used, since
  reaping happens automatically whenever a new session is created.
</ul>

<h3> Miscellaneous Utilities </h3>
<ul>
  <li> <a href="strip-tags.mhtml"><b>strip-tags</b></a>:
  A program which filters out every HTML and <meta-html> tag from its
  input.  Very useful in conjunction when creating search databases, or
  to produce a text file from an HTML or <meta-html> input file.
