+=head3 make_path( %args or \%args or @args )
+
+This is the counterpart to C<Maypole::parse_path>. It generates a path to use
+in links, form actions etc. To implement your own path scheme, just override
+this method and C<parse_path>.
+
+ %args = ( table => $table,
+ action => $action,
+ additional => $additional, # optional - generally an object ID
+ );
+
+ \%args = as above, but a ref
+
+ @args = ( $table, $action, $additional ); # $additional is optional
+
+C<id> can be used as an alternative key to C<additional>.
+
+C<$additional> can be a string, an arrayref, or a hashref. An arrayref is
+expanded into extra path elements, whereas a hashref is translated into a query
+string.

{
Only 1 named parameter is required but other than url, they can be combined as required and current values (from the request) will be used in place of any missing arguments. The url argument must be a full url including protocol and can only be combined with status.
