- * The meta data format used in pfSense is denoted using markers
- * followed by the appropriate value or value pair. All markers
- * are prefixed with a ##| sequence. The + suffix is used to
- * denote the beginning of a tag block followed by the tag name.
- * A - suffix is used to denote the end of a tag blaock. Values
- * are denoted using the * suffix and can optionally be expressed
- * as a key value pair. An example of a metadata tag block ...
- *
- * ###|+INFO
- * ###|*BLAH
- * ###|*TEXT=SOME TEXT
- * ###|-INFO
- *
- * After calling read_file_metadata, the result array would
- * contain the following information ...
- *
- * metadata['<filename>']['INFO']['BLAH'][0] == true
- * metadata['<filename>']['INFO']['TEXT'][0] == "SOME TEXT"
- *
- * NOTE: All statements must be at the begining of a line and
- * contiguous for a tag. The example shown above would not be
- * processed due to the extra ' * ' comment chars.
