Set defaut app based on file extension?
How can I tell my desktop (fedora-23/xfce4) to use Emacs to open
any file with a ".org" extension? Everything I've found on the
internet seems to set an application based on mimetype but ".org"
files are seen as "text/plain" (at least by the 'file' program)
and I don't want to open all text files with Emacs, just ".org"
ones. Thanks...
