/* This class should simplify the task of installing PEAR-packages, if you
 *  don't have a cgi-php binary on your system or you don't have access to
 *  the system-wide pear directory.
 *
 *  To use it, make the following php-script:
 *
 *  <?php
 *      require("PEAR/WebInstaller.php");
 *      $installer = new PEAR_WebInstaller("/path/to/your/install/dir","http://php.chregu.tv/pear/");
 *      $installer->start();
 *  ?>
 *
 *  and put PEAR/WebInstaller.php (this script) anywhere in your include_path.
 *
 *  (http://php.chregu.tv/pear/ is just for testing purposes until this
 *    system runs on pear.php.net, but feel free to use it till then)
 *
 *  Both parameters are optional. If the install dir is ommitted, the
 *  installer takes either the system wide pear-directory (mostly
 *  /usr/local/lib/php on unix), if it's writeable, or else the directory
 *  the script is started. Be advised, that the directory, where the
 *  PEAR::Packages will be installed, has to be writeable for the web-server.
 *
 *  The second parameter points to the server/directory where all the
 *  packages and especially Packages.xml is located. If not given, the
 *  standard PEAR-Repository is taken (http://pear.php.net/whatever..)
 *
 *  After installation, just add the install-dir to your include_path and
 *  the packages should work.
 *
 *  If you are System Adminisitrator and want the installed packages to be
 *  made available for everyone, just copy the files to the systemwide
 *  pear-dir after installation on the commandline. Or also add the
 *  install-dir to the systemwide include_path (and maybe don't forget to
 *  take the writeable off the directory..)
 *
 *  TODO:
 *      - More Error Detection
 *      - Grouping of Packages
 *      - Show installed Packages (from /var/lib/php/packages.lst?)
 *      - Add possibility to install a package (.tgz) from the local file
 *           system without a global Packages.xml (useful if no cgi-php
 *           around and you need this package you downloaded installed :) )
 *      - Search Function (maybe needed if we have hundreds of packages)
 *      - Only download Packages.xml, if it actually changed.
 *
 *  This Code is highly experimental.
