-k, --keycheck perform a keyboard check session (must be run from a\n\
plain console only, not from a pty/rxvt/xterm)\n\
-f, --find-package find the package to which FILE belongs\n\
-l, --list-package list contents of PACKAGE (or all packages if none given)\n\

-v, --verbose produce more verbose output\n\
-h, --help annotate output with explanatory comments when given\n\

-V, --version print the version of cygcheck and exit\n\
