New CTAN package: pst-diffraction

Herbert Voss has submitted another new pstricks package: > The authors of the package are Manuel Luque and Herbert Vo\ss > > This package allows to draw the diffraction patterns for different > geometric forms of apertures for monochromatic light. > The aperture stops can have rectangular, circular > or triangular openings. > The options available are the dimensions of the aperture > under consideration and of the particular optical > setting, e.g. the radius in case of an circular opening. > Moreover one can choose the wavelength > of the light (the associated color will be given > automatically by the package). > There are three commands, for rectangular, circular and > triangular openings respectively: > > \psdiffractionRectangle[settings] > \psdiffractionCircular[settings] > \psdiffractionTriangle[settings] > > The documentation is available in english, french, and german. i've installed the package and updated the catalogue. users may view the catalogue entry at http://www.tex.ac.uk/tex-archive/help/Catalogue/entries/pst-diffraction.html or browse the package directory at http://www.tex.ac.uk/tex-archive/graphics/pstricks/contrib/pst-diffraction/ (note that the documentation files are rather painfully large, and thus the zip of that directory is also pretty huge.) thank you, herbert and manuel, for the new package.
