 found in the 'tools' CVS module, or in the 'scummvm-tools' package.
 
+Some parts of ScummVM, particularly scalers, have highly optimized versions 
+written in assembler. If you wish to use this option, you will need to install 
+nasm assembler (see http://nasm.sf.net). Note, that currently we have only x86
+MMX optimized versions, and they will not compile on other processors.

 On Win9x/NT/XP you can define USE_WINDBG and attach WinDbg to browse debug
