-Tablizer supports plugins written in zygomys lisp. You can supply a
-directory to the \f(CW\*(C`\-l\*(C'\fR parameter containing \fB*.zy\fR files or a single
-\&.zy file containing lisp code.
-.PP
-You can put as much code as you want into the file, but you need to
-add one lips function to a hook at the end.
-.PP
-The following hooks are available:
-.IP "\fBfilter\fR" 4
-.IX Item "filter"
-The  filter hook  works  one a  whole  line of  the  input. Your  hook
-function is expected to return true  or false. If you return true, the
-line will be included in the output, otherwise not.
-.Sp
-Multiple filter hook functions are supported.

-Example:
