(S)ection (X)tractor aims to extract "sections" from a directory of files while respecting the original file structure.

A "section" is defined as anything which resembles the following structure:-

*---------------------------------------------------------------------------------------*
| Offset 	| Size	| Value								|
*---------------------------------------------------------------------------------------*
| 0x0		|  4	| FOURCC Identifier (ie. 'PVRT' for PowerVR textures)		|
| 0x4		|  4	| Size of section in bytes					|
*---------------------------------------------------------------------------------------*

By default, sx will find and extract PowerVR textures found in any of the input files (denoted by the PVRT FOURCC).. however, support for other sections can easily be added by adjusting the arrays at the top of sx.cpp.

Files are written to the input/current directory, with their FOURCC identifiers used as the file extension, or optionally to another directory with the third argument.

Additionally, sections can be added to sx by making use of sx.ini (placed in the same directory as the executable).

The below examples disables the built-in PVRT section and enables it through the configuration, for demonstration purposes. Section names are limited to 4 bytes/characters and must be ASCII (for now).

[general]
version=1
disable_pvrt=true
exclude_extensions=.XYZ,.ZZZ

[sections]
SectionName0=PVRT
SectionSize0=0

Example usage:-

* sx.exe "/path/to/files"
* sx.exe "/path/to/files" "/path/to/output"
