+- `-fastest` (which is equivalent to `-uastc_level 0`) puts the UASTC LDR/HDR encoders in their fastest (but lower quality) modes.
 
 - `-slower` puts the UASTC LDR/HDR encoders in higher quality but slower modes (equivalent to `-uastc_level 3`). The default level is 1, and the highest is 4 (which is quite slow).
 
 - `-q X`, where X ranges from [1,255], controls the ETC1S mode's quality vs. file size tradeoff level. 255 is the highest quality, and the default is 128.
 
 - `-debug` causes the encoder to print internal and developer-oriented verbose debug information.
 
-- `-stats` to see various quality (PSNR) statistics. 
+- `-stats` to see various quality (PSNR) statistics.
 
 - `-linear`: ETC1S defaults to sRGB colorspace metrics, UASTC LDR currently always uses linear metrics, and UASTC HDR defaults to weighted RGB metrics (with 2,3,1 weights). If the input is a normal map, or some other type of non-sRGB (non-photographic) texture content, be sure to use `-linear` to avoid extra unnecessary artifacts. (Angular normal map metrics for UASTC LDR/HDR are definitely doable and on our TODO list.)
