[kronolith] use new Kronolith HEAD

[DRIMM]

Hello,

I'm using the horde package from esup-portail because of CAS needed.

horde 3.0.4
Kronolith 2.0.3
Turba 2.0.2

Or I got problem with FreeBusy URL... The same problem identified by the 
ticket "[#2180] free/busy returns wrong values". (free/busy shows for 
"all attendees" only free "possible meeting times" (on green), no busy 
informations (on red) are shown).

The solution was: try a snapshot of Kronolith HEAD, and using 
kronolith-HEAD-2005-08-08 works fine.

I would like to know the procedure to upgrade my kronolith and use a new 
Kronolith HEAD.

I'm newbie on php...
