Go AppImage

An implementation of AppImage tools written in Go by the inventor of the AppImage format.

Documentation:

appimagetool, a tool to deploy dependencies into AppDirs (including things like Qt, Gtk, GStreamer,...) and to convert AppDirs into AppImages
appimaged, an optional daemon that integrates AppImages into the system, shows their icons, and makes them executable

Go follows the "keep it simple" principle - in line with what I like
Go compiles code to static binaries by default - no messing around with shared libraries that tend to break on some target systems (e.g., for converting SVG to PNG), no need to build in Docker containers with ancient systems for compatibility
Go does not need Makefiles, Autoconf, CMake, Meson - stuff that adds "meta work" which I don't like to spend my time on
Go is designed with concurrency and networking in mind - stuff that will come in handy for building in p2p distribution and updating
Go is something I want to learn - and one learns best using a concrete project

Get rid of C code embedded in Go
Get rid of external tools from https://github.com/probonopd/static-tools and replace with native Go
