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
