Probably shouldn't be in this PR but maybe okay to sneak in?

I actually did mean to write "sane", but since you're the second person (#3) to stumble across this, I'll change it.
Does "genuine" sound right?

Yes, I think genuine could work better than sane.

Add a script that extracts the demo code snippets from README.md and runs them in a shell, raising `SystemExit`, if the output is not as expected. This is an automated testing alternative to the existing `run_demo.py`, which replicates the commands from the demo instructions, with the advantage that the commands don't have to be synced. NOTE: The script requires the in-toto version specified in requirements.txt, i.e. 0.2.3 at the moment.
Adopt demo instructions to be used with newly created script that extracts snippets from fenced code blocks and runs them. This commit marks to snippets for exclusion, by specifying the snippet language, used for syntax highlighting, as `bash` (`run_demo_md.py` only extracts `shell` snippets). Plus some minor cleanup.
`tree` behaves (sorts) differently on different platforms, which is a problem, when testing against an expected output.
Requires changes in the expected output of the automated demo run script.
This is necessary to get the same output in different environments, which in turn is necessary to compare it to hardcoded expected output.
These are treated differently with `set -x` on different systems and thus break the build E.g. on Travis (ubuntu): `+ echo something evil` and locally: `+ echo 'something evil'`
Kudos to @CameronLonsdale and @adityasaky for pointing it out.

This PR adds a script that extracts the demo code snippets from
README.mdand runs them in a shell, raisingSystemExit, if the output is not as expected.Comparing outputs requires some minor modifications in the used commands (to make the output cross-platform deterministic). The PR further
In the future, automatic builds will also be triggered when a new version of in-toto is released (using
dependabot.In terms of testing this is an alternative to the existing
run_demo.pyscript (which just replicates the commands from README.md), with the advantage that now the commands don't have to besynced anymore.
If we decide to remove
run_demo.pywe might want to add a simple clean command, to remove files added during the demo, and consider live output (see comment aboutin_toto.process.run_duplicate_streamsinrun_demo_md.py).RELATED WORK: This is a rather custom solution for a problem that was also discussed in theupdateframework/python-tuf#808. A more generic tool, would need to allow different languages, e.g. shell and python (using
doctest) and maybe more options to customize the test success/fail conditions.
