 Building the source code

 To build ScummVM for PSP you need:
 
 - PSP toolchain	(svn co svn://svn.pspdev.org/psp/trunk/psptoolchain)
+
 - PSPSDK 	(svn co svn://svn.pspdev.org/psp/trunk/pspsdk)
+  		Note: This usually gets installed by the PSP toolchain,

 - SDL		(svn co svn://svn.pspdev.org/psp/trunk/SDL)

 - zlib		(svn co svn://svn.pspdev.org/psp/trunk/zlib)

+When you've installed these libraries (read their README.PSP for instructions),

 You can control most of the build process (engines and libraries used) from
 the Makefile.
