Introduction &TCD; provides support for different documentation formats, including Texinfo, LaTeX, DocBook and LinuxDoc. These formats have their own specifications and requirements to create and maintain documentation manuals written through them. Inside &TCAR;, the functionality provides an interface where documentation format specifications have been already considered for you to be able of creating and maintaining documentation manuals without needing to take care of those underlaying structuring tasks. This chapter describes how the functionality implements the different documentation source formats available inside &TCD;, and the internationalization issues related to documentation manuals produced through them.
