Veusz 2.0
---------
https://veusz.github.io

Veusz is a scientific plotting package.  It is designed to produce
publication-ready PDF or SVG output. Graphs are built-up by combining
plotting widgets. The user interface aims to be simple, consistent and
powerful.

Veusz provides GUI, Python module, command line, scripting, DBUS and
SAMP interfaces to its plotting facilities. It also allows for
manipulation and editing of datasets. Data can be captured from
external sources such as Internet sockets or other programs.

Changes in 2.0.1:
 * Fix crash setting manual bins in histogram dialog box
 * Add missing DLLs to Windows installer
 * Fix version number in Mac OS package
 * Add new colormaps (thanks to yingchaolu)

Changes in 2.0:
 * Update to PyQt5 and Qt5
 * Use Ghostscript to write EPS/PS formats
 * Use pyinstaller for MacOS builds instead of py2app
 * Windows build requires Windows 7 minimum
 * MacOS build requires MacOS 10.10 minimum
 * Move to using Sphinx for documentation
 * Add Makefile for documentation and remove build script
 * Use isfinite() on FreeBSD
 * Drop old veusz_listen script in favour of veusz --listen
