Ump-code
Functions which have this indication is written in a .ump file.
And to be able to use them you must have the folder ump-files
in your autoload-path in the Preferences-window, this should
already be the case if you installed Ump using 'make install'.
If that's not the case just add the folder so that Ump knows
where to look for the .ump-files and everything should be fine.
