In order for automation scripts to produce content inside a working copy of &TCAR;, it is required that all work lines be related somehow. The relation between work lines is used by automation scripts to know where to retrive the information they need to work with (e.g., input files, translation messages, output locations, etc.). This kind of relation is built using two path constructions known as master paths and auxiliar paths. A master path refers to a directory inside the repository that contain input files required to produce output files through automation scripts. Examples of master paths inside the repository include: trunk/Identity/Models/Brands trunk/Manuals/Tcar-ug trunk/Identity/Models/Themes/Default/Distro/5/Anaconda An auxiliar path refers to directories inside the repository considered auxiliar for one single master path. Auxiliar path can be either for output or localization. Assuming the master path provides the input information, the auxiliar paths provide the auxiliar information which describes how and where that input information must be rendered by automation scripts. Examples of auxiliar paths inside the repository include: trunk/Identity/Images/Brands trunk/Manuals/Tcar-ug/es_ES trunk/Locales/Manuals/Tcar-ug/es_ES trunk/Identity/Images/Themes/Flame/3/Distro/5/Anaconda/es_ES trunk/Locales/Identity/Models/Default/Distro/5/Anaconda/es_ES The relationship between master and auxiliar paths is built by combining the second directory level of master paths with directories in the second directory level of repository layout. In the second directory level of repository layout, the Identity, Manuals and Scripts directories are always used to create the master paths and the output auxiliar paths. The Locales directory, on the other hand, is always used to create localization auxiliar paths for all the master paths available under Identity, Manuals and Scripts directories. For example, if the LANG environment variable is set to es_ES.UTF-8 and you execute the render functionality of centos-art.sh script with the trunk/Manuals/Tcar-ug master path as argument, it will produce &TCARUG; in Spanish language using translation messages from trunk/Locales/Manuals/Tcar-ug/es_ES auxiliar path and would save final documentation output files under trunk/Manuals/Tcar-ug/es_ES auxiliar path.
