This included file (version \stripRCS$Revision: 3.7 $) provides a \PS\
interface for the effects defined in the |style| extension.

\DOCHEADER
\paragraph*{\PS\ Style lists}
Note: The contents of the style lists |\preXY@style@| and |\postXY@style@|
should be `raw' \PS\ code.
This prevents |\special|s from being inserted twice, once by |\Connect@@|
and once by |\Drop@@|, with straight lines using |\xyPSstraight@|.

The <driver>-file must call the following macro to rebind a control sequence
defined in |xystyle|, thereby allowing the \PS\ mechanisms to be used.
