file: 00README G. Moody 3 April 2001 Last revised: 25 April 2005 The most recent version of 'plt' is always freely available from PhysioNet (http://physionet.org/physiotools/plt/). `plt' is a non-interactive plotting utility originally written for Unix by Paul Albrecht. `plt' can produce publication-quality 2D plots in PostScript from easily-produced text or binary data files under Unix, Linux, MacOS/X, or MS-Windows. These can be printed directly on a PostScript printer, or they can be viewed on-screen or printed on a wide variety of non-PostScript printers using GhostScript. `plt' can also produce screen plots under any version of Unix, Linux, MacOS/X or MS-Windows, if an X Window System server is running. `plt' is free software, available under the terms of the GNU Public License (GPL); see `COPYING' for details. The `src' directory contains sources for `plt', its X11 and PostScript drivers, and its auxiliary programs. The `doc' directory contains the `plt Tutorial and Cookbook' in ready-to-print PDF and LaTeX source format, as well as data and format files for a large number of examples that may be helpful as models for your own plots. You may also read the `plt Tutorial and Cookbook' by pointing your web browser to `index.html' in the `html' directory (note, however, that the translation from LaTeX source to HTML format was done with an automatic translator, and the formatting is not perfect). The `misc' directory contains several small programs that are useful together with `plt', including `pltf' (which can plot functions of a single variable expressed in symbolic form). Older versions of `plt' also included drivers for a variety of mostly obsolete graphics terminals and plotters. These drivers are still available in the `classic' directory, but they are no longer maintained and lack many of the features of the X11 and PostScript drivers. For instructions on compiling and installing `plt', read `INSTALL'. For information about using `plt', read `QUICKSTART'. Your comments are welcome! Please send them to george@mit.edu.
