 *  Copyright (C) 2001-2003 Tom Gutwin

 *
 *   - Macro to create and preview the JavaDocs for the current buffer
 *   - It tries to figure everything out for you.
 *   - Map this macro to it to a button on the button bar and away you go!
 *
 * ************************************************************************
 * ** Requires the Console plugin and the InfoViewer plugin
 * ** ALSO
 * ** Requires Downloading of the different doclets if you are going to use
 *    them and pdfReaderCommand if using the pdfDoclet.
 * ***********************************************************************
 * **  Features
 * ***********************************************************************
 *
 *   - most of the settings to customize how this macro performs are set with
 *     boolean flags (see code below).  The following features are some of the
 *     features already selectable/customizable
 *
 *   - javadoc of current buffer OR current buffer's package
 *       set the 'doFullPackage'  boolean flag in the macro code
 *       You can then save a copy of this macro as a different name
 *       for example...  Preview_JavaDoc_Of_Current_Buffers_Package.bsh
 *
 *   - default Doclet is the standard Java Doclet
 *     (the user can change the default doclet to use by changing the XXXX
 *      variable in this macro)
 *
 *   - When this macro starts, a doclet choice dialog is presented.
 *     this dialog can be bypassed by setting 'showDocletDialog' to false
 *     see the code below
 *
 *   - Many of the standard Doclet commandline parms are preset with some
 *     defaults...     header, footer etc.
 *     They are all controlled via boolean flags in the code
 *     Switch them on/off as you like.
 *
 *   - Includes the ability to use 'user selectable' doclets
 *     The following are already built in. (you just have to go get the doclet)
 *      > the DocBook doclet - dbdoclet  http://www.michael-a-fuchs.de
 *      > the Bouvard Doclet - http://web.tiscali.it/no-redirect-tiscali/farello/bp/intro.html
 *      > the XMLDoclet - http://
 *      > the pdfdoclet (Java API to PDF) - http://sourceforge.net/projects/pdfdoclet
 *      > others
 *
 *   - easy selection of output dir (defaults to system temp dir)
 *     set with the 'outputDir' var in the macro code
 *
 *   - other standard doclets parameters have been supervised by variables.
 *     see below for adding extra classpath, source path, title, header, footer
 *     MORE below
