[horde] Differences between Horde head files and what is written in the install file

[Marco Maiani]

I'm trying to install Horde head  but I found that there are various 
differences from what is written in the Install file and the files that 
I found in the tar.gz. For example there isn't any horde/framework 
directory with any install-packages.php like is written in install file. 
Is the install file too old ?
