The texlive package provides only the binaries; all symlinked commands,
macros, and documentation are provided by the texlive-collection-*
packages, which mostly correspond to the individual TeX Live packages
installed by each of the collection-* meta-packages. (Most of the
hyphen-* packages are empty except for a postinstall command which isn't
necessary for us. That's why a few collection-lang* aren't packaged,
since they include only those empty hyphen-* packages.) I'll be happy
to explain anything which isn't clear about these packages.
