+ Words Of Worship Song File Format
+ `````````````````````````````````
+
+ The Words Of Worship song file format is as follows:
+
+ * The song title is the file name minus the extension.
+ * The song has a header, a number of blocks, followed by footer containing
+ the author and the copyright.
+ * A block can be a verse, chorus or bridge.
+
+ File Header:
+ Bytes are counted from one, i.e. the first byte is byte 1. These bytes,
+ up to the 56 byte, can change but no real meaning has been found. The
+ 56th byte specifies how many blocks there are. The first block starts
+ with byte 83 after the "CSongDoc::CBlock" declaration.
+
+ Blocks:
+ Each block has a starting header, some lines of text, and an ending
+ footer. Each block starts with 4 bytes, the first byte specifies how
+ many lines are in that block, the next three bytes are null bytes.
+
+ Each block ends with 4 bytes, the first of which defines what type of
+ block it is, and the rest which are null bytes:
+
+ * ``NUL`` (\x00) - Verse
+ * ``SOH`` (\x01) - Chorus
+ * ``STX`` (\x02) - Bridge
+
+ Blocks are seperated by two bytes. The first byte is ``SOH`` (\x01),
+ and the second byte is ``€`` (\x80).
+
+ Lines:
+ Each line starts with a byte which specifies how long that line is,
+ the line text, and ends with a null byte.
+
+
+ Footer:
+ The footer follows on after the last block, the first byte specifies
+ the length of the author text, followed by the author text, if
+ this byte is null, then there is no author text. The byte after the
+ author text specifies the length of the copyright text, followed
+ by the copyright text.
+
+ The file is ended with four null bytes.
+
+ Valid extensions for a Words of Worship song file are:
+
+ * .wsg
+ * .wow-song
