 * 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.

 * 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"

 *

 * processed due to the extra ' * ' comment chars.
