To dump an IWI:
 IWITool.exe IWI t5_weapon_m60e3_env.iwi DIR T5Test 

To recompile a dumped IWI:
 IWITool.exe DIR T5Test IWI Recompiled.iwi 

To create a brand new IWI (Sample pixel format: RGBA:512x512x6):
 IWITool.exe NEW [PixelFormat - PIXELTYPE:WIDTH:HEIGHT:SURFACES] DIR newTest 13 

To convert an IWI with a single surface to another game:
 IWITool.exe IWI t5_weapon_m60e3_env.iwi IWI T6.iwi 27 

To compile a BMP (NOT RECOMMENDED):
The correct flags can be obtained from dumping a similar IWI. 
You may want to experiment with removing or adding 3, 2 bitwise flags to your flag depending on the game. 
 IWITool.exe BMP [FLAGS] [GAMMA] test.bmp IWI Test.iwi 27
