[horde] help : recommended PECL modules for HGWE

[Keepshango]

Hello,

I am blocked at section with *recommended PECL modules for Horde 
Groupware Webmail Edition* !


I first need to understand the way that both “*extension“* and 
*“module“* terms are used.

*Q1 : *Do they mean the same thing ?
*Q2 :* Or, is term “extension“ only apply if the extension is paired 
with a server  ?


The *memcache extension is paired with memcached server* that must be 
previously installed.

*Q3 :* Is each of other extensions (*imagick*, *horde_lz4*, *http*) also 
paired with a server ?
*Q4 :* Or does each of other extensions only require common dedicated 
packages to be installed ?


*Q5 :* Does each extension needs a related *directive to be added in 
php.ini file*, e.g. *“extension=memcached.so“* as observed in this 
tutorial for Install the PHP Memcached Extension
