+/**\r
+ * <p>\r
+ * Manager and initializer of the properties required by SLC Ant.\r
+ * </p>\r
+ * \r
+ * <p>\r
+ * All properties described here will get a value one way or another (see below\r
+ * for details)/ Each property will be accessible via Ant or Spring properties.\r
+ * </p>\r
+ * \r
+ * <p>\r
+ * The property <i>slc.rootFile</i> is set based on the location of the SLC\r
+ * root property file found in the directory structure of a called Ant file. The\r
+ * default name of this file is <b>slcRoot.properties</b> (can be set by\r
+ * {@link #setSlcRootFileName(String)}). <br>\r
+ * This property provides the absolute path to the unique SLC root property file\r
+ * which marks the root of an Ant SLC tree structure.\r
+ * </p>\r
+ * \r
+ * <p>\r
+ * The property <i>slc.rootDir</i> is inferred from <i>slc.rootFile</i> and\r
+ * provides a convenient shortcut to the root directory of the Ant files\r
+ * directory structure.\r
+ * </p>\r
+ * \r
+ * <p>\r
+ * A few directory and file related properties can be set in the SLC root\r
+ * property file (if they are not explicitly set their default values will be\r
+ * used):\r
+ * \r
+ * <table border="1" cellspacing="0">\r
+ * <tr>\r
+ * <th>Property</th>\r
+ * <th>Description</th>\r
+ * <th>Default</th>\r
+ * </tr>\r
+ * <tr>\r
+ * <td><i>slc.confDir</i></td>\r
+ * <td>Directory where to find the various configuration files of a given SLC\r
+ * Ant deployment</td>\r
+ * <td>${slc.rootDir}/../conf</td>\r
+ * </tr>\r
+ * <tr>\r
+ * <td><i>slc.workDir</i></td>\r
+ * <td>Directory where data can be retrieved or generated: build outputs, test\r
+ * inputs/outputs, test results, etc. The underlying directory structure is\r
+ * specified by the specific SLC application.</td>\r
+ * <td>${slc.rootDir}/../work</td>\r
+ * </tr>\r
+ * <tr>\r
+ * <td><i>slc.propertyFileNames</i></td>\r
+ * <td>Comma-separated list of the files names of the property files to load\r
+ * from the conf directory. Having various files allows to separate between SLC\r
+ * framework properties and properties specific to a given application built on\r
+ * top of SLC. All will be available across Ant and Spring.</td>\r
+ * <td>slc.properties</td>\r
+ * </tr>\r
+ * </table> <b>Note:</b> Only the properties above can be set in the SLC root\r
+ * properties file. All other properties should be defined in the registered\r
+ * conf files.\r
+ * </p>\r
+ * \r
+ * <p>\r
+ * Any property can be defined in the conf files defined in the SLC root\r
+ * properties file (see above). SLC expects some which will have defaults but\r
+ * can be overriden there. By convention they should be defined in the\r
+ * <b>slc.properties</b> file, while application specific properties should be\r
+ * defined in other conf files. This allows for a clean spearation between SLC\r
+ * and the applications built on top of it:\r
+ * \r
+ * <table border="1" cellspacing="0">\r
+ * <tr>\r
+ * <th>Property</th>\r
+ * <th>Description</th>\r
+ * <th>Default</th>\r
+ * </tr>\r
+ * <tr>\r
+ * <td><i>slc.applicationContext</i></td>\r
+ * <td>Path to the root Spring application context file used by SLC Ant.</td>\r
+ * <td>${slc.confDir}/applicationContext.xml</td>\r
+ * </tr>\r
+ * <tr>\r
+ * <td><i>slc.defaultTestRun</i></td>\r
+ * <td>Name of the {@link WritableTestRun} Spring bean that the\r
+ * <code>slc.test</code> task will use by default. This can be overridden when\r
+ * calling the task from Ant.</td>\r
