autogen output I don't understand

[Jean-Charles Malahieude]

Hi !

Here is what I get on a fresh clone (Fedora 15 box).
Do I have to fear about it?

address@hidden Lily]$ git clone -l -s -n . ../Mentors
Cloning into '../Mentors'...
done.
address@hidden Lily]$ cd ../Mentors/
address@hidden Mentors]$ git reset --hard
HEAD is now at dd63de6 Release: bump version.
address@hidden Mentors]$
