Runtime: wx.app.mainLoop and twisted reactor now share main thread with runtime.Worker.
This fixes exception when invoking python interactive shell from Runtime's tray
icon right-click menu.
Probably a consequence of wxPython upgrade, together with initial bad idea to
move wx.app.mainloop in non-main thread.
Project overview
================
In order to target the widest possible range of programmable devices and keep efficient, Beremiz use C code as an intermediate language.
To be executed, C needs to be compiled. `GCC <http://gcc.gnu.org>`_ serve that purpose perfectly.
PLC program is expressed in languages defined in IEC-61131, including graphical languages. Thanks to PLCopen TC2, those graphical languages have a standardised representation, in XML.
To be continued.
