* This class is used to classify the given file using some magic bytes

|

* The magic file consists of ASCII characters defining the magic numbers for

|
* (those starting with a hash character) are ignored. Columns are described

|
* o <b>2</b> -- type of data to match. Can be one of following
|
||||||
|
* - <i>byte</i> (single character)
|
||||||
|
* - <i>short</i> (machine-order 16-bit integer)
|
||||||
|
* - <i>long</i> (machine-order 32-bit integer)
|
||||||
|
* - <i>string</i> (arbitrary-length string)
|
||||||
|
* - <i>date</i> (long integer date (seconds since Unix epoch/1970))
|
||||||
|
* - <i>beshort</i> (big-endian 16-bit integer)
|
||||||
|
* - <i>belong</i> (big-endian 32-bit integer)
|
||||||
|
* - <i>bedate</i> (big-endian 32-bit integer date)
|
||||||
|
* - <i>leshort</i> (little-endian 16-bit integer)
|
||||||
|
* - <i>lelong</i> (little-endian 32-bit integer)
|
||||||
|
* - <i>ledate</i> (little-endian 32-bit integer date)
|
||||||
|
* o <b>3</b> -- contents of data to match
|
||||||
|
* o <b>4</b> -- file description/MIME type if matched
|
||||||
|
* o <b>5</b> -- optional MIME encoding if matched and if above was a MIME type
