== OCaml debugging ==

I have added debugging features to the 1.41 SVN version of kprl.  This is controlled by the verbosity level.  Level 1 is not very noisy, level 2 is extremely noisy.

I have also found the XOR-key for CLANNAD FV which is 0xAF2FFB6BAF3077178748FE2C681AB9F0.  In order to disassemble make sure to specify the version, 1.5.0.4. Example:
 kprl.exe --target-version=1.5.0.4 -y AF2FFB6BAF3077178748FE2C681AB9F0 -e utf-8 -d SEEN.txt

Patch for both is below:
