+ * Pure-PHP ANSI Decoder
+ *
+ * PHP versions 4 and 5
+ *
+ * If you call read() in Net_SSH2 you may get {@link http://en.wikipedia.org/wiki/ANSI_escape_code ANSI escape codes} back.
+ * They'd look like chr(0x1B) . '[00m' or whatever (0x1B = ESC). They tell a
+ * {@link http://en.wikipedia.org/wiki/Terminal_emulator terminal emulator} how to format the characters, what
+ * color to display them in, etc. File_ANSI is a {@link http://en.wikipedia.org/wiki/VT100 VT100} terminal emulator.
