[horde] Installing 2 copies of Horde4

[Andrew Morgan]

I know I'm running late to the Horde4 party, but my time has been soaked 
up with other projects.  Now, I'm finally getting around to upgrading from 
Horde3 to Horde4.

I have 2 installs of Horde3 (plus IMP, Turba, Kronolith, Mnemo, and Nag) 
on my servers - one in /var/www/horde/ and one in /var/www-test/horde/.  I 
normally test any upgrades and changes in www-test before rolling them 
over to www.

Is there a recommended way to do 2 installs of Horde4?  The INSTALL docs 
offer a hint in section 3.2 - Installing into separate PEAR.  Is that the 
way to go about this?

Thanks,
 	Andy
