/**
 * PEAR_PackageFileManager2, like PEAR_PackageFileManager, is designed to
 * create and manipulate package.xml version 2.0.
 *
 * The PEAR_PackageFileManager2 class can work directly with PEAR_PackageFileManager
 * to create parallel package.xml files, version 1.0 and 2.0, that represent the
 * same project, but take advantage of package.xml 2.0-specific features.
 *
 * Like PEAR_PackageFileManager, The PEAR_PackageFileManager2 class uses a plugin system
 * to generate the list of files in a package. This allows both standard recursive
 * directory parsing (plugin type file) and more intelligent options
 * such as the CVS browser {@link PEAR_PackageFileManager_Cvs}, which
 * grabs all files in a local CVS checkout to create the list, ignoring
 * any other local files.
 *
 * Example usage is similar to PEAR_PackageFileManager:
 * <code>
 * <?php
 * require_once('PEAR/PackageFileManager2.php');
 * PEAR::setErrorHandling(PEAR_ERROR_DIE);
 * //require_once 'PEAR/Config.php';
 * //PEAR_Config::singleton('/path/to/unusualpearconfig.ini');
 * // use the above lines if the channel information is not validating
 * $pfm = new PEAR_PackageFileManager2;
 * // for an existing package.xml use
 * // $pfm = {@link importOptions()} instead
 * $e = $pfm->setOptions(
 * array('baseinstalldir' => 'PhpDocumentor',
 * 'packagedirectory' => 'C:/Web Pages/chiara/phpdoc2/',
 * 'filelistgenerator' => 'cvs', // generate from cvs, use file for directory
 * 'ignore' => array('TODO', 'tests/'), // ignore TODO, all files in tests/
 * 'installexceptions' => array('phpdoc' => '/*'), // baseinstalldir ="/" for phpdoc
 * 'dir_roles' => array('tutorials' => 'doc'),
 * 'exceptions' => array('README' => 'doc', // README would be data, now is doc
 * 'PHPLICENSE.txt' => 'doc'))); // same for the license
 * $pfm->setPackage('MyPackage');
 * $pfm->setSummary('this is my package');
 * $pfm->setDescription('this is my package description');
 * $pfm->setChannel('mychannel.example.com');
 * $pfm->setAPIVersion('1.0.0');
 * $pfm->setReleaseVersion('1.2.1');
 * $pfm->setReleaseStability('stable');
 * $pfm->setAPIStability('stable');
 * $pfm->setNotes("We've implemented many new and exciting features");
 * $pfm->setPackageType('php'); // this is a PEAR-style php script package
 * $pfm->addRelease(); // set up a release section
 * $pfm->setOSInstallCondition('windows');
 * $pfm->addInstallAs('pear-phpdoc.bat', 'phpdoc.bat');
 * $pfm->addIgnoreToRelease('pear-phpdoc');
 * $pfm->addRelease(); // add another release section for all other OSes
 * $pfm->addInstallAs('pear-phpdoc', 'phpdoc');
 * $pfm->addIgnoreToRelease('pear-phpdoc.bat');
 * $pfm->addRole('pkg', 'doc'); // add a new role mapping
 * $pfm->setPhpDep('4.2.0');
 * $pfm->setPearinstallerDep('1.4.0a12');
 * $pfm->addMaintainer('lead', 'cellog', 'Greg Beaver', 'cellog@php.net');
 * $pfm->setLicense('PHP License', 'http://www.php.net/license');
 * $pfm->generateContents(); // create the <contents> tag
 * // replace @PHP-BIN@ in this file with the path to php executable! pretty neat
 * $test->addReplacement('pear-phpdoc', 'pear-config', '@PHP-BIN@', 'php_bin');
 * $test->addReplacement('pear-phpdoc.bat', 'pear-config', '@PHP-BIN@', 'php_bin');
 * $pkg = &$pfm->exportCompatiblePackageFile1(); // get a PEAR_PackageFile object
 * // note use of {@link debugPackageFile()} - this is VERY important
 * if (isset($_GET['make']) || (isset($_SERVER['argv']) && @$_SERVER['argv'][1] == 'make')) {
 * $pkg->writePackageFile();
 * $pfm->writePackageFile();
 * } else {
 * $pkg->debugPackageFile();
 * $pfm->debugPackageFile();
 * }
 * ?>
 * </code>
 *
 * In addition, a package.xml file can now be generated from
 * scratch, with the usage of new options package, summary, description, and
 * the use of the {@link addLead(), addDeveloper(), addContributor(), addHelper()} methods

/**
 * Set package.xml generation options
 *
 * The options array is indexed as follows:
 * <code>
 * $options = array('option_name' => <optionvalue>);
 * </code>
 *
 * The documentation below simplifies this description through
 * the use of option_name without quotes
 *
 * Configuration options:
 * - lang: lang controls the language in which error messages are
 * displayed. There are currently only English error messages,
 * but any contributed will be added over time. 
 * Possible values: en (default)
 * - packagefile: the name of the packagefile, defaults to package.xml
 * - pathtopackagefile: the path to an existing package file to read in,
 * if different from the packagedirectory
 * - packagedirectory: the path to the base directory of the package. For
 * package PEAR_PackageFileManager, this path is
 * /path/to/pearcvs/pear/PEAR_PackageFileManager where
 * /path/to/pearcvs is a local path on your hard drive
 * - outputdirectory: the path in which to place the generated package.xml
 * by default, this is ignored, and the package.xml is
 * created in the packagedirectory
 * - filelistgenerator: the <filelist> section plugin which will be used.
 * In this release, there are two generator plugins,
 * file and cvs. For details, see the docs for these
 * plugins
 * - usergeneratordir: For advanced users. If you write your own filelist
 * generator plugin, use this option to tell
 * PEAR_PackageFileManager where to find the file that
 * contains it. If the plugin is named foo, the class
 * must be named PEAR_PackageFileManager_Foo
 * no matter where it is located. By default, the Foo
 * plugin is located in PEAR/PackageFileManager/Foo.php.
 * If you pass /path/to/foo in this option, setOptions
 * will look for PEAR_PackageFileManager_Foo in
 * /path/to/foo/Foo.php
 * - changelogoldtonew: True if the ChangeLog should list from oldest entry to
 * newest. Set to false if you would like new entries first
 * - simpleoutput: True if the package.xml should be human-readable
 * - clearchangelog: True if change log should not be generated/updated
 * - addhiddenfiles: True if you wish to add hidden files/directories that begin with .
 * like .bashrc. This is only used by the File generator. The CVS
 * generator will use all files in CVS regardless of format
 *
 * package.xml simple options:
 * - baseinstalldir: The base directory to install this package in. For
 * package PEAR_PackageFileManager, this is "PEAR", for
 * package PEAR, this is "/"
 * - changelognotes: notes for the changelog, this should be more detailed than
 * the release notes. By default, PEAR_PackageFileManager uses
 * the notes option for the changelog as well
 *
 * WARNING: all complex options that require a file path are case-sensitive
 *
 * package.xml complex options:
 * - ignore: an array of filenames, directory names, or wildcard expressions specifying
 * files to exclude entirely from the package.xml. Wildcards are operating system
 * wildcards * and ?. file*foo.php will exclude filefoo.php, fileabrfoo.php and
 * filewho_is_thisfoo.php. file?foo.php will exclude fileafoo.php and will not
 * exclude fileaafoo.php. test/ will exclude all directories and subdirectories of
 * ANY directory named test encountered in directory parsing. *test* will exclude
 * all files and directories that contain test in their name
 * - include: an array of filenames, directory names, or wildcard expressions specifying
 * files to include in the listing. All other files will be ignored.
 * Wildcards are in the same format as ignore
 * - roles: this is an array mapping file extension to install role. This
 * specifies default behavior that can be overridden by the exceptions
 * option and dir_roles option. use {@link addRole()} to add a new
 * role to the pre-existing array
 * - dir_roles: this is an array mapping directory name to install role. All
 * files in a directory whose name matches the directory will be
 * given the install role specified. Single files can be excluded
 * from this using the exceptions option. The directory should be
 * a relative path from the baseinstalldir, or "/" for the baseinstalldir
 * - exceptions: specify file role for specific files. This array maps all files
 * matching the exact name of a file to a role as in "file.ext" => "role"
 * - globalreplacements: a list of replacements that should be performed on every single file.
 * The format is the same as replacements
 * - globalreplaceexceptions: a list of exact filenames that should not have global
 * replacements performed (useful for images and large files)
 * note that this is not exported to package.xml 1.0!!
