It was done as we used to also do 'crafty' executables which were dos-files. starting with version 17.0, we will only have 'crafty.exe' type files, without the w. The source files are the same for _all_ systems... 2. crafty doesn't build the databases, that is Eugene's code. Crafty wouldn't need any modifications to use the 6 man files you are suggesting, assuming that someone has the time to modify the generator... However, modifying that code is non-trivial without a lot of 'reading'.
