    <title>Connection between directories</title>

    <para>In order for automation scripts to produce content inside

    working copies of CentOS Artwork Repository, it is required that

    all work lines be connected somehow.  Using this connection,

    automation scripts can know where to retrive the information they

    need to work with (e.g., design model, translation messages,

    output locations, etc.).  This connection is built using two path

    constructions named <emphasis>master paths</emphasis> and

    <emphasis>auxiliar paths</emphasis>.</para>

    <para>The master path points only to directories that contain

    source files (e.g., SVG files) required to produce base content

    (e.g., PNG files) through automation scripts.  Each master path

    inside the repository may have several auxiliar paths associated,

    but auxiliar paths can only have one master path associated.

    Master paths are organized under 

    class="directory">trunk/Identity/Models</filename> directory

    structure and auxiliar paths under 

    class="directory">trunk/Identity/Images</filename>, 

    class="directory">trunk/Locales</filename> and 

    class="directory">trunk/Manuals</filename> directory

    structures.</para>

    <para>The auxiliar paths can point either to directories or files.

    When an auxiliar path points to a directory, that directory

    contains information that modifies somehow the content produced

    from master paths (e.g., translation messages) or provides the

    output information required to know where to store the content

    produced from master path.  When an auxiliar path points to a

    file, that file has no other purpose but to document the master

    path it refers to.</para>

    <para>The relationship between auxiliar paths and master paths is

    realized by combining the master path itself and the second level

    directory structures of the repository.  The master path is

    considered the path identifier and the second level directory

    structure taken from the repository is considered the common part

    of the path where the path identifier is appended to.</para>
