I believe that it would be great if the directive "IncludeConf" will be implemented to the pacman configuration.

It will be useful if an user has several pacman configurations which differ only in repository settings (e.g. special configuration for for [testing] repositories), for example. It allows an user maintains only one main configuration with ignore lists, paths, etc. I'd like to suggest the following implementation:

/etc/pacman.conf <- main configuration
/etc/pacman-with-testing-enabled.conf <- additional configuration
/etc/pacman.conf.in <- common declarations

cat /etc/pacman.conf.in
<snip>
IgnorePkg = pacman
<snip>

cat /etc/pacman{,-with-testing-enabled}.conf
<snip>
IncludeConf = /etc/pacman.conf.in
# the ignore option is already declared in the include file
#IgnorePkg =
<snip>

As a possible implementation I believe that the include file may be just placed as plain text replacing the "IncludeConf" string. As an additional feature it would be great if this option may be set multiple times.
