Links to some excellent little known programs that I used in making the files below.
A great FREE solution to Micro$oft Office is WPS Office [Formaly called
KingSoft] which is a cross platform program for Windows, iOS [iPad , iPod &
iPhone], Android and Linux.
Reads & writes Office 97 to 2010 formats, and outputs in all plus
PDF. http://www.wps.com/
Graphisme et utilitaires - PhotoFiltre ver 6.53 [Photoshop Clone] [in Downloads - which is located in top left Left column]
http://photofiltre.free.fr/frames_en.htm Extract to anywhere and run. Nice program and features. Simple editing & easy to use
Schindler & Shill Gmbh - GerberLogix V29 Gerber viewer - great program
