Some rules for the code layout and its development.

• Everything is under Apache 2 license, see fle LICENSE.
• All sources must be unix-text files: https://en.wikipedia.org/wiki/Text_file
  • Lines end in {LF}.
  • The files are either empty or end in {LF}.
• All code must be formatted using the relevant formatters, as enforced by pre-commit.
  • This provides consistent formatting.
  • The choices are meant to enable fast structural reading by humans.
  • It cares less about writing because there is auto formatting and code is
    read much more often then written.
  • Auto formatting also prevents pointless discussions like where '*' goes.
  • The guide mostly follows Google style: https://google.github.io/styleguide/
• All exported library code is in the directory 'bzl'.
• All public / exported code must:
  • be tested,
  • have a documentaion.
• API changes that are not backwards compatible should not occur in minor version changes.
• Undocumented and private/internal APIs may be changed in any way at any time.
