Since @immelman at least *was* using the AUR package at some point, in addition to that, it also installs as /usr/bin/escribe-suite if you want to launch from console, but both ways work, Launcher in the Application menu as well as launching through commandline.
Debian and Ubuntu and their derivatives should work reasonably well, though I don't know about it running on a Raspi, it being ARM based. That might pose an issue.
@meti
GTK2 doesn't allow for proper scaling unfortunately.
GTK3 would be able to scale/change the scaling for a single application when using the GDK_SCALE environment variable.
@Gelmo technically, in this case it isn't even compiling freshly, since no source is available. It is plainly converting whichever mono binaries and libraries are redistributed by Evolv/James through the installer from the first post and putting them in a pacman compatible package archive.
