The XDG files depend on the package manager and desktop manager which is 
why I didn't add them to swiki.

Here are the files I use for Ubuntu 16.04 (64bit). I store squeak 
related launchers in /opt/share/bin to keep the OS and my apps on 
separate volumes, so I have to modify .xsessionrc to include this path. 
bashrc is not sufficient because GUI programs may not start a shell.
----- .xsessionrc ------
case "$PATH" in
	*/opt/share/bin:*) ;;
	*) PATH=/opt/share/bin:$PATH ;;
esac
------------------------
(Logout and login to read this .rc file)

I then copy squeak5.png icon into /usr/share/pixmaps and then install 
the desktop file with:

----- squeak-vm.desktop ----
[Desktop Entry]
Type=Application
Name=Squeak VM
Exec=run %F
Icon=squeak
Categories=Development;
MimeType=application/spur-image;application/cog-image;application/stack-image;application/squeak-image;application/cog64-image;application/spur64-image;application/squeak64-image
--------------------------
$ xdg-desktop install squeak-vm.desktop

The mimes are generated as explained in the thread:
