To install Crime Patrol, unzip all the files to a temp directory.  Then,
type "ZCP CP-01.AS /R" to construct the LIB file.  After which, edit the game.cfg
to match your system (ie, path definitions and sound blaster settings).
You can delete *.AS after installation.

When playing, left mouse button fires and right mouse button reloads (when
you have the cross hairs over the bullet marker in the bottom right hand 
side of the screen)
