Version 0.91 of PSTricks was announced to users on a mailing list
after its completion last June, but this is the first "public"
announcement because I was away for the summer.

The most important change is that the \dbox macro has been
replaced by a collection of very powerful and flexible node
connection macros, which are good for trees, mathematical
diagrams, and connecting information.

There are also some new graphics objects, including an arc
object that allows arrowsheads, and various curve interpolation
objects.

For those who are new, PSTricks is a kitchen sink of PostScript-
based TeX macros. Among other things, it is probably the most
powerful TeX drawing package around. It can be used with
most TeX macro packages, including Plain TeX, LaTeX, AmS-TeX
and AmS-LaTeX.

Attached are a read-me file, and the TeX input and PostScript output
for a test file, to give you a taste of the package.

PSTricks is available via anonymous ftp from the /pub directory
at Princeton.EDU. You should also pick up pstricks.bug from the
same place. Despite the warning at the beginning of the readme
file, this release has proved to be stable.

DESCRIPTION:

  pstricks.tex is an extensive collection of PostScript macros that is
  compatible with most TeX macro packages, including Plain TeX , LaTeX
  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.
  * Nested rotations can be made with respect to the physical page.
  * There is 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 lets you have your cake (TeX) and eat it too (PostScript)!

FILES:

  Inputs:
    pstricks.tex : The main macro file, for use with a header file.
    pstricks.sty : The same as pstricks.tex, but the .sty extension.
    pstricks.con : The configuration file for pstricks.tex.

  Documentation:
    pst-usr1.ps  : User's Guide, part I.
    pst-usr2.ps  : User's Guide, part II.
    pst-test.tex : A test file.
    pst-read.me  : This file.

  Sources:
    pstricks.doc : Documentation and code for pstricks.tex.
    pst-code.tex : For typesetting pstricks.doc.
    pst-user.tex : User's Guide.
    tvz-hax.sty  : Macros for printing documentation.
    2up.tex      : More macros for printing documentation.
    npsfont.sty  : Used for printing the User's Guide.
    pst-make.tex : For making a stripped input file and header file.

  Header:
    pstricks.pro : A PostScript prologue (for use with dvips).

INSTALLATION FOR USERS OF ROKICKI'S DVIPS:

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

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

  3. Print pst-usr1.ps and pst-usr2.ps, which is the User's Guide
     for pstricks.tex. The last few pages of pst-usr2.ps
     are a Quick Reference.

  4. Have fun!

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

  PSTricks has only been tested extensively with Rokicki's dvips.
  However, it should be able to adapted to other drivers with
  similar capabilities.

  1. Print the User's Guide.

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

  3. Examine the configuration file pstricks.con. Uncomment
     the \iffalse...\fi surrounding the commands for 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. When satisfied, run pst-make with Plain TeX or LaTeX. Put the
     file pstricks.tex that is generated where you TeX looks for inputs,
     along with pstricks.con and pstricks.sty. If you opt to generate
     and use a header file, put this where your dvi driver looks for
     such a beast. Then define \pstheader properly in the configuration
     file. PSTRicks works much more quickly and generates smaller
     PostScript files when used with the header file.

UPGRADING FROM PREVIOUS VERSIONS:

  Much has changed. You should reinstall the package in its entirety.
  As previously announced, \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
  "Changes" section below 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.
  (However, the commentary is currently out of date.)

  If you want to modify the internals of PSTricks, don't use a
  PostScript header file (i.e., don't use \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 defined \pstheader in pstricks.con.

USING PSTRICKS WITH SUN' PAGEVIEW/NEWSPRINT/OPENWINDOWS

  Sun's PageView/NeWSPrint/OpenWindows have many bugs,
  especially with the wrong combination of versions.
  Workarounds for several of these have been coded into
  PSTricks. However, arrows may sometimes do odd things
  when used in landscape mode with dvips. Report other problems
  to tvz@Princeton.

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 a mailing list for PSTricks to
  tvz@Princeton.

PSTRICKS.TEX AND SEMINAR.STY

  The PSTricks package grew out of macros originally written for the
  Seminar 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 v0.91 works with seminar.sty version 0.92, and maybe later
  versions as well. The Seminar package is also available from
  Princeton.EDU, and perhaps from wherever else you got PSTricks.

ACKNOWLEDGEMENTS:

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

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

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

COPYING:

  Copying of part or all of any file in the pstricks package
  is allowed under the following conditions only:
  (1) You may freely distribute unchanged copies of the files. Please
      include the documentation when you do so.
  (2) You may modify a renamed copy of any file, but only for personal
      use or use within an organization.
  (3) You may copy fragments from the files, for personal use or for use
      in a macro package for distribution, as long as credit is given
      where credit is due.

  You are NOT ALLOWED to take money for the distribution or use of
  these files or modified versions or fragments thereof, except for
  a nominal charge for copying etc.

BUGS:

  Too many to list, and who knows what they are anyway. These files are all
  preliminary and unstable. Not for use as children's sleepware.

  Please report bugs, enhancements and other comments, especially positive
  or negative experiences with DVI-to-PS converters and previewers, to

             Timothy Van Zandt, [e-mail].

  Thanks.

CHANGES:

Policy: These macros are preliminary, but future incompatible changes
to the user interface will be minimized. (A promise broken once already.)

Key: In listings below,
    + means addition,
    * means change,
    ! means change that may cause problems with old files.

v.9: Much internal code was changed, and additional features were added.
  See the User's Guide for details.

 ! The syntax of \dline has changed several times.

 ! With \multido, the backslash should now be included with variable
   names in the variable declarations.

 * Memory stats with LaTeX's article style:
    40179 words of memory
     2740 multiletter control


v.91:

 * In spite of the many new features, the input file is smaller in bytes,
   and runs significantly faster (at least if used with a header file).
   The macros use up slightly more words of memory, and significantly
   more command sequences. Here are the stats with LaTeX's article
   style:
     41586 words of memory
      2966 multiletter control sequences

 ! \dbox and \rotate eliminated.

 ! \psput replaced by \rput, with new syntax:
      OLD:  \psput[angle]<ref point>(x,y){stuff}
      NEW:  \rput[ref point]{angle}(x,y){stuff}
   \OldPsput sets up \psput with the old syntax (this may disappear some
   day; keep it in a safe place if you expect to need it for a long time).

 ! System for specifying angles for nested rotations with \psput has changed.
      OLD:  p0{angle}, p1{angle}, p2{angle}, etc.
      NEW:  *angle  works like p0{angle}; p1{angle} capability eliminated.
   N, S, E and W have same meaning as before.

 ! enddotsize parameter changed to dotsize.

 ! For specifying the origin as the baseline for the \pspicture
   environment, leave the optional argument [] empty (rather than
   [o]).

 ! B is not allowed as the y-coordinate when setting the reference point
   in \rput using coordinates. E.g., [Bl] and [B] are OK, but [.3,B] is
   not.

 * \sunpatch not needed anymore.

 * PostScript header file (if being used) is included at the beginning,
   rather than on demand.

 + cornersize parameter added, for specifying whether radius of corners
   in \psframe and related box macros is given in relative terms (using
   framearc) or absolute terms (using linearc).

 + \psclip and \clipbox macros added.

 + \Cartesian and \Polar commands added, for switching coordinate
   systems.

 + border=dim parameter added, for giving appearance of one line
   crossing over another.

 + showpoints=bool parameter added. If true, a dot is placed at appropriate
   coordinates.

 + \psdots graphics object added.

 + \psarc graphics object added.

 + \parabola graphics object added.

 + \pscurve, \psccurve, \psecurve, \psdoodle, \psedoodle, and \pscdoodle
   graphics objects added.

 + \qline and \qdisk graphics objects added.

 + \psplot, \parametericplot and \listplot graphics objects added.

 + node connection (e.g., tree) macros added!!
