18 * Manager and initializer of the properties required by SLC Ant.
22 * All properties described here will get a value one way or another (see below
23 * for details)/ Each property will be accessible via Ant or Spring properties.
27 * The property <i>slc.rootFile</i> is set based on the location of the SLC
28 * root property file found in the directory structure of a called Ant file. The
29 * default name of this file is <b>slcRoot.properties</b> (can be set by
30 * {@link #setSlcRootFileName(String)}). <br>
31 * This property provides the absolute path to the unique SLC root property file
32 * which marks the root of an Ant SLC tree structure.
36 * The property <i>slc.rootDir</i> is inferred from <i>slc.rootFile</i> and
37 * provides a convenient shortcut to the root directory of the Ant files
38 * directory structure.
42 * A few directory and file related properties can be set in the SLC root
43 * property file (if they are not explicitly set their default values will be

59 * <td><i>slc.workDir</i></td>
60 * <td>Directory where data can be retrieved or generated: build outputs, test
61 * inputs/outputs, test results, etc. The underlying directory structure is
62 * specified by the specific SLC application.</td>

67 * <td>Comma-separated list of the files names of the property files to load

80 * properties file (see above). SLC expects some which will have defaults but
81 * can be overriden there. By convention they should be defined in the
82 * <b>slc.properties</b> file, while application specific properties should be
83 * defined in other conf files. This allows for a clean spearation between SLC
