Scribus is a desktop publishing program (DTP) that is [free software](https://www.gnu.org/philosophy/free-sw.en.html) licensed under the GNU General Public License. It is cross-platform: There are versions available for GNU/Linux, Mac OS X, OS/2, and Windows. This makes Scribus suitable for minor to medium audience publications, which were designed collaboratively in non-corporate organizations. The current stable version is 1.4.6. SLA files are the native format for Scribus. You can export files into PDF, EPS, SVG and raster images.
This book is addressed to readers who are not yet familiar with any DTP software. Applications like OpenOffice, LibreOffice, and MS Word are word-processing software, not desktop publishing software. Word processors are concerned primarily with editing text. Desktop publishing software is concerned primarily with layout (e.g. placement of columns, images, headlines, etc.)
