Appion

h1. Download additional Software

h3. 3.1 Install the additional package repositories 

*NOTE*

There are several additional CentOS repositories that you can install.

These repositories provide additional packages, such as patented software (MP3 players),

closed source applications (Flash plugin, Adobe Acrobat Reader)

and lesser used packages (python numpy, Gnu Scientific Library).

But some repositories install packages over other packages,

which can cause problems and conflicts (ATrpms is bad at this). So I recommend only installing

EPEL and RPM Fusion. Read more here:

"CentOS Additional Repositories":http://wiki.centos.org/AdditionalResources/Repositories 

h4. 3.1.1 Extra Packages for Enterprise Linux (EPEL) 

* http://fedoraproject.org/wiki/EPEL

* contains a wealth of packages required for appion

.Download repository rpm and install

<pre>

$ sudo rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/`uname -i`/epel-release-5-3.noarch.rpm

</pre>

h4. 3.1.2 RPM Fusion 

* http://rpmfusion.org/

* good for mp3 and other patent limited software

.Download repository rpms and install

<pre>

$ sudo rpm -Uhv http://download1.rpmfusion.org/free/el/updates/testing/5/`uname -i`/rpmfusion-free-release-5-0.1.noarch.rpm

$ sudo rpm -Uvh http://download1.rpmfusion.org/nonfree/el/updates/testing/5/`uname -i`/rpmfusion-nonfree-release-5-0.1.noarch.rpm

</pre>

h3. 3.2 Update current packages 

.Update the updater to make life easier

</pre>

.Update all packages

<pre>

</pre>

*NOTE*

Download was over 129 MB (in July 2009). If you have a slow internet connection you can setup presto/deltarpms, "see this email]":http://www.linux-archive.org/centos-development/222706-presto-deltarpm.html 

You may want to restart your computer when this completes.
