[Andreas Tille]

Hi Tim,

I forgot to CC you.  If you want to contribute to this discussion please
respond to the bug report.  I admit I consider ea-utils quite a bad name
choice but I'm afraid we can not convince ea-utils upstream.  Or do you
have some contacts and can point this out?

Kind regards

      Andreas.

Subject: Re: Bug#794334: ea-utils: /usr/bin/alc already used by amule-utils-gui

Hi,

I just learned that there is a name space conflicts with the new package
ea-utils and amule-utils-gui.  I know that we are working according to a
first comes first served basis and thus ea-utils would be responsible to
rename this file.  However, I would like to ask you anyway whether there
is any chance to deal with this name space conflict from the amule-utils
side.

Kind regards

        Andreas.
