/**
 * PageGenerator command line main class.
 * For example:
 * <pre>
 * Usage:
 *   PageGenerator urlListFile [savePath [skipFolder [proxyHost [proxyPort]]]]
 * Downloads web pages specified in urlListFile to the folder named by
 * savePath.  Uses proxyHost and proxyPort, if specified, as the proxy server
 * for accessing web sites outside your firewall.
 * savePath is the folder in which PageGenerator saves output files:
 * if not specified, it uses PageGenerator's own folder.
 * If skipFolder is specified and numeric, PageGenerator shortens the URL by
 * that many levels (see EXAMPLES).
 * With extension ".txt", urlListFile contains space-delimited pairs of
 * URLs and filenames:
 *   http://localhost/magazine/project.asp?RECORD_INDEX=3 project.index3.html
 * With any other extension, urlListFile contains an HTML table, with the URL
 * in the leftmost column, the filename in the rightmost column, and URL
 * arguments specified in the intermediate columns (if any) -- in this case
 * the table's first row contains the URL arguments names.
 *   <table>  <!-- 2-column version -->
 *   <tr><td>http://localhost/magazine/project.asp?RECORD_INDEX[Features]=3</td>
 *       <td>project.index3.html</td></tr>
 *   </table>
 * or
 *   <table>  <!-- argument-columns version -->
 *   <tr><td>(ignored)</td>
 *       <td>RECORD_INDEX[Features]</td>  <!-- argument name -->
 *       <td>(ignored)</td></tr>
 *   <tr><td>http://localhost/magazine/project.asp
 *       </td><td>3</td>                  <!-- argument value -->
 *       <td>project.index3.html</td></tr>
 *   </table>
 * EXAMPLES
 *   java PageGenerator c:\\temp\\urls.txt c:\\temp\\saved-site
 * Reads URLs, saves output files in c:\\temp\\saved\\saved-site (creates
 * folder if necessary).
 *   java PageGenerator http://myhost/my-list-page.asp c:\\temp\\saved-site
 * Reads a URLs from HTML dynamically generated by my-list-page.asp.
 *   java PageGenerator /tmp/urls.txt /tmp/saved-site
 * UNIX (MacOS X) usage.  If filenames contain spaces or other special
 * characters, quote them: "/tmp/My Folder/urls.txt"
 *   java PageGenerator /tmp/urls.txt /tmp/saved-site 1
 * As above, but saves URLs like http://myhost/a/b/c.html as
 * /tmp/saved-site/b/c.html, not /tmp/saved-site/a/b/c.html
 *   java PageGenerator /tmp/urls.txt /tmp/saved-site 0 myproxy 8080
 * Uses the proxy server http://myproxy:8080 to access URLs.
