DESCRIPTION:

  pstricks.tex is an extensive collection of PostScript macros that is
  compatible with most TeX macro packages, including Plain TeX , LaTeX
  AmSTeX and AmS-LaTeX. Included are macros for color, graphics, rotation,
  trees and overlays. It has several special features:
 

    * There is a wide variety of graphics (picture drawing) macros, with
      a flexible interface and with color support. All lines and outlines
      can be solid, dotted or dashed. Lines and curves can have arrowheads,
      t-bars, brackets or circles on the ends. Regions can be filled
      with solid colors, lines or crosshatch.
    * There is support for polar and cartesian coordinate systems.
    * There are macros for plots and axes.
    * Nested rotations can be made with respect to the physical page.
    * There are flexible node macros, useful for trees, mathematical
      diagrams, and linking information of any kind.
    * There is a powerful loop macro that is useful for making pictures.
    * There are macros for coloring or shading the cells of tables.

  PSTricks puts the icing (PostScript) on your cake (TeX)!

GETTING PSTRICKS

  The PSTricks package is available from the /pub directory at
  Princeton.EDU, and at other archives.
 

  A bug list pstricks.bug is kept up-to-date on Princeton.EDU.
 

  Send requests to get on or off the PSTricks mailing list to the author.

PRINTING THE USER'S GUIDE:

  The User's Guide is distributed in PostScript format as
  pst-usr1.ps and pst-usr2.ps. There is also a quick reference,
  pst-quik.ps.
 

  Sun Newsprint/Pageview users: See relevant section below.

  For printing on a4 paper: See relevant section below.

  The User's Guide uses less than 150K of virtual memory, which is well
  below the minimal PostScript configuration. If you run out of memory,
  try turning off the printer to flush out stuff left in memory
  from previous jobs.
 

  Any other problems printing pst-usr1.ps and pst-usr2.ps should be
  reported to me. However, you are on your own if you choose
  to typeset the LaTeX source (pst-user.tex). LaTeXing pst-user.tex
  is NOT a good way to test PSTricks, as there are too many other
  macros involved.

PRINTING THE USER'S GUIDE ON A4 PAPER:

  You may find that it prints fine as is, but you might want to try making
  the following changes to the .ps files (this stuff is printer dependent):
 

  Change these lines:
   

       OLD:
       %%BoundingBox: 0 0 612 792
       TeXDict begin 40258431 52099146 1000 300 300 @start /Fa 134[33
       NEW:
       %%BoundingBox: 0 0 596 842
       TeXDict begin 39158280 55380996 1000 300 300 @start /Fa 134[33
 

  Add this just before %%EndComments:
 

     %%DocumentPaperSizes: a4
    

  Add these just before %%EndSetup.
 

     %%BeginPaperSize: a4
     a4
     %%EndPaperSize
    

INSTALLATION FOR USERS OF ROKICKI'S DVIPS:

  1. Put the input files where your TeX looks for inputs.
    

  2. Put the file pstricks.pro where dvips looks for headers.
     Probably /usr/lib/tex/ps on unix systems.
   

  3. Typeset the LaTeX file samples.pst as a test and to see the samples.
 

  3. Have fun!

INSTALLATION FOR USERS OF ARBORTEXT'S DVIPS AND TEXTURES:

  1. Examine the configuration file pstricks.con. Uncomment
     the \iffalse...\fi surrounding the commands for Rokicki's dvips.
     Comment out the \iffalse...\fi surrounding the commands for
     Arbortext's dvips or Textures.
    

  2. If using Textures, decide whether you want to use a header file.
     Uncomment the definition of \pstheader if you do.
    

  3. Run pst-make through Plain TeX or LaTeX. This generates
     pstricks.tex and possibly pstricks.pro.
    

  4. Follow the instructions above for Rokicki's dvips, using
     the pstricks.tex and pstricks.pro files that you generated
     rather than the ones that came with the package.
    

INSTALLATION FOR USERS OF OTHER DVI-TO-PS DRIVERS:

  PSTricks should be adaptable to other drivers with similar capabilities.
  Feel free to contact me for help.

  1. Use pstricks.doc as your input file for now (rather than pstricks.tex).
 

  2. Examine the configuration file pstricks.con. Uncomment
     the \iffalse...\fi surrounding the commands for Rokicki's dvips.
     Try to define the required commands appropriately for you driver,
     but don't use a header file yet (i.e., leave \pstheader
     undefined).
   

  3. Run pst-test.tex through Plain TeX until you get things to work
     as well as possible. You may not be able to use all of PSTricks features,
     but if you can define \pstverb and \pstunit, you at least can use
     all the graphics objects.
 

  4. Decide whether your driver supports inclusion of a PostScript
     header file. (PSTricks runs much more efficiently with a header,)
     If so, define \pstheader appropriately in pstricks.con.
    

  5. Run pst-make through Plain TeX or LaTeX. This generates
     pstricks.tex and possibly pstricks.pro.
 

  6. Follow the instructions above for Rokicki's dvips, using
     the pstricks.tex and pstricks.pro files that you generated
     rather than the ones that came with the package.

UPGRADING FROM VERSION 0.91:

  You need to reinstall the package in its entirety, including
  pstricks.pro. There are a few incompatible changes, described in
  changes.pst. The User's Guide is greatly improved -- check it out.
 

UPGRADING FROM VERSION 0.9 OR EARLIER:

  Much has changed. You should reinstall the package in its entirety.
  \dbox and \rotate have been removed. \psput has been replaced by \rput,
  with new syntax. However, the command \OldPsput defines \psput to work
  with the old syntax; the command \NewPsput defines \psput to work with
  the new syntax. See the pst-chan.ges for more information.
 

TIPS FOR HACKERS:

  The file pstricks.doc contains the documentation and code, using
  Frank Mittelbach's doc system. You can typeset this, if desired,
  by running LaTeX on pst-code.tex. See pst-code.tex for details.
  Don't expect too much from the documentation.
 

  If you want to modify the internals of PSTricks, don't use a
  PostScript header file (i.e., don't define \pstheader in pstricks.con)
  and use pstricks.doc as your input file. This allows you to modify
  both the TeX and the PostScript macros.
 

  When you don't expect to make more changes for a while, run
  pst-make to generate a new compact macro file and a new
  PostScript header file (if desired). If using a header file,
  don't forget to redefine \pstheader in pstricks.con.

  Beware that the internal code in PSTricks is still unstable.
 

USING PSTRICKS WITH SUN'S PAGEVIEW/NEWSPRINT/OPENWINDOWS

  Sun's PageView/NeWSPrint/OpenWindows have many bugs.
  Workarounds for several known problems of these have been coded into
  PSTricks. A workaround for another bug is described below. Report other
  problems to me.

  A bug under Sun's PageView/NeWSprint 3.0 (perhaps fixed in 3.0.1),
  causes arrows to disturb the lines. To see if you have this problem,
  try previewing the section in pst-usr2.ps on axes. Here is a workaround:
 

  If using a header, append the  following to pstricks.pro:

    /EndArrow { x2 y2 currentpoint grestore angle matrix identmatrix
    rotate transform y1 add exch x1 add exch end } def

  Do this in pst-usr1.ps and pst-usr2.ps as well.

  If not using a header file, add the following to the end of pstricks.con:
 

    \pst@def{EndArrow}<%
      x2 y2 currentpoint grestore
      angle matrix identmatrix rotate transform
      y1 add exch x1 add exch end>

PSTRICKS AND SEMINAR.STY

  The PSTricks package grew out of macros originally written for the
  seminar.sty package.  seminar.sty is a LaTeX style for slides and notes.
  seminar.sty, combined with pstricks.tex and your favorite macros for
  inclusion of EPS files, make a complete TeX presentation software package.
 

  PSTricks v0.92 works with seminar.sty version 0.92, and maybe later
  versions as well. The seminar.sty package is also available from
  Princeton.EDU, and perhaps from wherever else you got PSTricks.

ABOUT MULTIDO.TEX:

  multido.tex contains a loop macro that is useful for making pictures,
  among other things. See multido.ps for details. multido.tex is required
  by PSTricks \psaxes macro.
 

  The complete multido.tex distribution (i.e., including sources) is
  available from the /pub directory at Princeton.EDU.
 

ACKNOWLEDGEMENTS:

  The basic idea for the node macros is from Emma Pease's tree-dvips.sty.
 

  The algorithm in the \pscurve macro was adapted from a C program by
  Shamim Zvonko Mohamed.
  

  Thanks to Geoffrey Tobin for helpful comments.
 

  The author is thankful to Frank Mittelbach for his  documentation system.
 

  Thanks to various contributors to samples.pst.
 

DISCLAIMERS:

  This is just an elaborate hack. Not for use as children's sleepware.
