How To Get A Global Menu In MATE Desktop

MATE GlobalMenu is an applet forked from the old GNOME2 GlobalMenu project, which adds a global menu to the MATE panel.
Mate GlobalMenu is based off the upstream GNOME GlobalMenu v0.7.10 and it only supports GTK2 applications, so don't expect Firefox, LibreOffice or Qt applications to work with this, but it's nevertheless an useful addition to the MATE desktop, especially for small screens.
