String ERROR a String representation for error.
String FALSE a String representation of false.
String FIELD_ATTRIBUTE_PFX the format of a field attribute name.
String KEEP a String representation for keep.
String KEEP_FILE_ORDER decide if all elements shall transmit in their original order.
String LATEST a String representation for latest.
String METHOD_ATTRIBUTE_PFX the format of a method attribute name.
String MODIFICATION_TIME if it shall attempt to determine the latest modification time if this is set to LATEST.
String PASS a String representation of pass.
String PASS_FILE_PFX the file that will not be compressed.
String PROGRESS packer progress as a percentage.
String SEGMENT_LIMIT The number of bytes of each archive segment.
String STRIP a String representation of strip.
String TRUE a String representation of true.
