[PHP] PEAR Packages

[Don]

Hi,
 
I have just started to explore PEAR.  I am using PHP 4.3.11 and so PEAR
automatically comes with PHP.  I would like to install PEAR's DB classes.
However, I cam right now browsing the PEAR web site and cannot find
information on how to install a package.  I have also downloaded and opened
the DB tgz file but there is no install document.
 
Can someone point me to the proper URL that explains how to install a PEAR
package?
 
Thanks,
Don
