It uses rather simple sed commands, but seems to work well enough.
+ Improve readme.
+ Shortened comments about why 3 lines.

This directory contains tox scripts and other files they need.
Generally, a tox script is either a checker (suitable for automated verify)
or a fixer (manually started, risky as uncommitted edits can be lost).
+
+In the tox verify job we want to avoid running fixers,
+as they can affect what other checkers see
+(e.g. autogen fixer could add more too long lines).
+That is why we keep fixers separate from checkers in principle,
+even for fairly safe tasks (e.g. bumping copyright years).
+
Each tox script is assumed to be run from tox,
when working directory is set to ${CSIT_DIR}.
+ Only the output suitable for automated processing by an external caller
should be written to stdout.
++ The level of "less verbose" depends on check and state of codebase.
-+ TODO: Should we carefully document which files are
- whitelisted/blacklisted for a particulat check?
Each fixer script should:
+ Perform edits on current filesystem
+ Not assume git is clean (there may be uncommitted edits).
+ Use "git diff HEAD~" to get both comitted and uncomitted edits to analyze.
+ Output whatever it wants (possibly nothing).
-
-TODO: Should checkers be named differently than fixers?
- E.g. both scripts and tox environments start with fix_?
