/**
 * Configuration of runtime classpath normalization.
 *
 * <p>Several methods accept a file pattern to selectively normalize files.  Patterns may include:</p>
 *
 * <ul>
 *
 * <li>'*' to match any number of characters
 *
 * <li>'?' to match any single character
 *
 * <li>'**' to match any number of directories or files
 *
 * </ul>
 *
 * <p>Either '/' or '\' may be used in a pattern to separate directories. Patterns ending with '/' or '\' will have '**'
 * automatically appended.</p>
 *
 * <p>Examples:</p>
 *
 * <pre>
 * all files ending with '.json' (including files in subdirectories)
 *    &#42;&#42;&#47;&#42;.json
 * </pre>
 *
 * <pre>
 * all files beginning with 'build-' in the level1/level2 directory
 *    level1/level2/build-&#42;
 * </pre>
 *
 * <pre>
 * all files (including subdirectories) beneath config/build-data
 *   config/build-data/
 * </pre>
 *
 * <pre>
 * all properties files in a build directory beneath com/acme (including subdirectories)
 *   com/acme/&#42;&#42;&#47;build/&#42;.properties
 * </pre>
