-=head1 LISP PLUGINS [experimental]
 
-Tablizer supports plugins written in zygomys lisp. You can supply a
-directory to the C<-l> parameter containing B<*.zy> files or a single
-.zy file containing lisp code.
-
-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.
-
-The following hooks are available:
-
-=over
-
-=item B<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.
-
-Multiple filter hook functions are supported.
-
-Example:
-    
-    /*
-    Simple filter hook function. Splits the argument by whitespace,
-    fetches the 2nd element, converts it to an int and returns true
-    if it s larger than 5, false otherwise.
-    */
-    (defn uselarge [line]
-      (cond (> (atoi (second (resplit line ` +`))) 5) true false))
-    
-    /* Register the filter hook */
-    (addhook %filter %uselarge)
-
-=item B<process>
-
-The process hook function gets a table containing the parsed input
-data (see C<lib/common.go:type Tabdata struct>. It is expected to
-return a pair containing a bool to denote if the table has been
-modified, and the [modified] table. The resulting table may have less
-rows than the original and cells may have changed content but the
-number of columns must persist.
-
-=item B<transpose>
-
-not yet implemented.
-
-=item B<append>
-
-not yet implemented.
-
-=back
-
-Beside the existing language features, the following additional lisp
-functions are provided by tablizer:
-
-    (resplit [string, regex]) => list
-    (atoi    [string])        => int
-    (matchre [string, regex]) => bool
-
-The standard language is described here: L<https://github.com/glycerine/zygomys/wiki/Language>.
