[CentOS-docs] Details on centos-art.sh required packages

[Alain Reguera Delgado]

Russ,

Could you move the following information

---
+ Preliminary required packages for '''centos-art.sh''':  The 
configuration script expects a working '''sudo''' environment, 
'''gettext''', '''texinfo-tex''', and the presence of '''/usr/bin/vim''' 
  As such install the following (at a minimum) with yum:
- {{{yum -y install sudo vim-enhanced gettext
+ {{{yum -y install sudo vim-enhanced gettext texinfo-tex
   }}}
---

from the wiki to the centos-art.sh documentation?

The centos-art.sh preparation process is being documented at 
`trunk/Manuals/Tcar-ug' directory, specifically in the 
`trunk/Manuals/Tcar-ug/Scripts/Bash/prepare.docbook' file.

It would be nice if we keep http://wiki.centos.org/ArtWork as simple as 
possible. All the package administration must be handle inside the 
prepare functionality and described in its documentation boundaries. The 
wiki must provide a simple start point for people to get involved.
