Rename repository documentation manual from `Repository' to
    `RepoUserguide': 
    
        - Two manuals come to my mind right now:
    
            1. The CentOS Artwork Repository -- User Guide:
            
                - Provides (e.g., it is completly built by hand).
                  task-oriented information about the repository. How to
                  accomplish specific things inside it.
    
                - Uses DocBook XML as documentation backend.
    
                - This manual is independent from repository directory
                  structure. There is no direct relation between the
                  repository directory structures and the documentation
                  structure itsefl. So, the `help' functionality of
                  centos-art.sh script doesn't control the
                  creation/maintainance of this documentation structure in
                  none way.
    
            2. The CentOS Artwork Repository -- References: 
            
                - Provides detailed technical information about the
                  repository. What each directory inside the repository is
                  for, the concepts behind it, how automation scripts
                  work.
    
                - Uses Texinfo as documentation backend.
    
                - This manual is dependent from repository directory
                  structure. There is one documentation entry for each
                  directory inside the repository. This way, the `help'
                  functionality of centos-art.sh script does control the
                  creation/maintainance of this documentation structure in
                  its whole extension (indeed, there is no other purpose
                  for the `help' functionality but to do this, and do it
                  well).
    
        - All other manuals will be created using DocBook XML DTD.
