TeX Directory Structure
The TeX Directory Structure (TDS) specifies a convention for organizing the files of TeX-related packages in a directory tree. The root of this tree, which is called the TEXMF root directory, usually contains one ore more of the following sub-directories:
bibtex/bibbibtex/bstfonts/afmfonts/encfonts/mapfonts/opentypefonts/pfbfonts/sourcefonts/tfmfonts/type1fonts/vftex/generictex/latextex/lualatextex/luatextex/plaintex/xelatex
For example, the LaTeX input files of package foo are expected to be found in tex/latex/foo/.
