+The package pst-optexp is a collection of optical components
+that facilitate easy sketching of optical experimental
+setups. Mechanisms for proper alignment of different components are
+provided internally. This way the user does not have to care for proper
+orientation of the elements.
+
+This is version 1.0, the first official release.

+\section{Introduction}
+The package \texttt{pst-optexp} is a collection of optical components
+that facilitate easy sketching of optical experimental
+setups. Mechanisms for proper alignment of different components are
+provided internally. This way the user does not have to care for proper
+orientation of the elements.
+
+\section{Components}
+
+In the following sections \ref{sec:mirror}--\ref{sec:custom} the
+available components with their parameters are described. Up to now
+there are two types of components: those which require two reference
+points and do not alter the direction of the passing light beam (for
+example lenses and retardation plates) and those which work in
+reflection and require three reference points (mirrors, grids,
+beamsplitters etc.).
+
+In section \ref{sec:general} general parameters are described that are not proprietary
+to a specific unit but can be used for several different components. Finally, in
+section \ref{sec:labels} the options for the positioning of labels are
+explained.
+
+\subsection{Lens}\label{sec:lens}
+
+\begin{description}
+\item[\param{lensheight} (dimension):] (\emph{default:~\texttt{1}})
+\item[\param{lenswidth} (dimension):] (\emph{default:~\texttt{0.3}})
+\item[\param{lenstype} (plainconvex, plainconcave, convexplain, concaveplain, biconvex, biconcave):] (\emph{default:~\texttt{biconvex}})
+\item[\param{lensradius} (dimension):] (\emph{default:~\texttt{\cs{empty}}})
+\end{description}
+
+For the convex lenses only two parameters are used. If the
+parameter \parameter{lensradius} is set, its value will be used together
+with \parameter{lensheight} to draw the
+lens. Otherwise \parameter{lenswidth} and
+\parameter{lensheight} are used. For concave lenses all three parameters
+are needed.

+
+The parameter \parameter{angle} is available for the macros \cs{optbox}
+and \cs{crystal} only, as for the most other cases it would make
+no sense. \parameter{optional} can be used with every component and marks it as
+optional and can be configured by changing the psstyle \parameter{OptionalStyle}.
+\parameter{position} is equivalent to the \parameter{npos} parameter of \cs{ncput},
+but is used only for the \lq dipole\rq-macros to position the component
+between the two given points. In addition, there is a parameter
+\parameter{abspos} that allows absolute positioning between the two line
+points. \parameter{showoptdots} shows in black the two points calculated for the
+positioning of the component, and in red the reference point for the
+label.

+\section{Known bugs}
+ 
+For some reason, filling of the concave lenses by
+specifiying \parameter{fillstyle} does not work properly. For sure there
+are other bugs, but they are not known, yet. If you find some, do not
+hesitate to contact me.
+
+\section{ Todo}
+
+\begin{itemize}
+\item Add components for fiber optics.
+\end{itemize}
+
+Drawing of extended beams with focusing, and so on, is not planned to be
+integrated in the near future due to missing ideas for the realization.

+%   Some of the components need three points to be positioned. 
+%   These are:

+%       1. startpoint of the beam (in the PS-Code: (XA,YA))
+%       2. reflectionpoint on the surface (XG, YG)
+%       3. endpoint (XB,YB)
+%
+%  With these three points \pst@calcNodes calculates two new points 'tempNode@A' 
+%  and 'tempNode@B', between which the component is placed by the macro 
+%  \pst@draw@component in the way, that 'angle of incidence' == 'angle of deflection'
+%  regarding the reflection surface (mirror, diagonal of the beamsplitter, 
+%  grid etc.)
