Short summary for input files of TeNeS
---------------------------------------

Input files of TeNeS are written in `TOML <https://github.com/toml-lang/toml/blob/master/versions/ja/toml-v0.5.0.md>`__ format
and each file has some sections.
``tenes_simple`` and ``tenes_std`` read some sections and generate an input file for ``tenes_std`` and ``tenes``, respectively.
``tenes`` reads some sections and performs simulation.

For example, ``tenes_simple`` reads ``model`` and ``lattice`` sections and generates ``tensor``, ``observable``, and ``hamiltonian`` ones.
Additionary, this copies ``parameter``, ``correlation``, and ``correlation_length`` sections.

The following table summarizes how each tool deal with sections.

  ``hamiltonian``, "out",  "in",      ""
  ``evolution``,   "",     "out",     "in"

- "in"

  - Tool uses this section as input

- "out"

  - Tool generates this section in output (= next input)

- "copy"

  - Tool copies this section into output (= next input)
