/*
|

* SLB support routines for PhysicsFS.
|
||||
*
|
||||
* This driver handles SLB archives ("slab files"). This uncompressed format
|
||||
* is used in I-War / Independence War and Independence War: Defiance.
|
||||
*
|
||||
* The format begins with four zero bytes (version?), the file count and the
|
||||
* location of the table of contents. Each ToC entry contains a 64-byte buffer
|
||||
* containing a zero-terminated filename, the offset of the data, and its size.
|
||||
* All the filenames begin with the separator character '\'.
|
||||
