Email reader for RISC OS operating system.
Pluto is an email and newsgroup reader for the RISC OS operating system (see http://www.riscosopen.org/), developed by Jonathan Duddington from 1997 to 2004. It stores emails and news articles in Boxes, and they can be Listed, Viewed, Written, Spell checked, Replied to, Searched and even Spoken out loud! After Pluto was released under GPLv3 in 2013, it has had many improvements. Thanks to Jonathan, all the changed source is hosted here on SourceForge. Pluto runs on older ARM processors eg Risc PC & Iyonix, as well as newer ARM processors eg Raspberry Pi, Beagleboard, Pandaboard, ARMX6 and Titanium, under any version of RISC OS later than v3.10. From v3.16 the RISC OS version of eSpeak is not included in the Pluto download, but separately in the Files espeak directory. The espeak project itself is on http://espeak.sourceforge.net, but seems currently dormant. For fuller details of all updates since v3.06b, please see the Pluto Web Site on http://www.avisoft.f9.co.uk/pluto
