-/**
- * LoggerAppenderRollingFile writes logging events to a specified file. The
- * file is rolled over after a specified size has been reached.
- *
- * This appender uses a layout.
- *
- * ## Configurable parameters: ##
- *
- * - **file** - Path to the target file.
- * - **append** - If set to true, the appender will append to the file,
- * otherwise the file contents will be overwritten.
- * - **maxBackupIndex** - Maximum number of backup files to keep. Default is 1.
- * - **maxFileSize** - Maximum allowed file size (in bytes) before rolling
- * over. Suffixes "KB", "MB" and "GB" are allowed. 10KB = 10240 bytes, etc.
- * Default is 10M.
- * - **compress** - If set to true, rolled-over files will be compressed.
- * Requires the zlib extension.
