This is the initial prototype for 🩹 Plaster. This work is based on a
recenlty worked out proposal:
https://docs.google.com/document/d/1aPf7cMB5Pc_ssKFC_I4-mLHr-7D4lTqsvItSXY-WzQM/
Run this tool with:
```
tools/cr/plaster.py
```
The tool at the moment is in a very early prototyping stage, and there
are many tickets opened for it, to get it into a mature state. The
intent is to manage to deliver this in gradual steps, while acquiring
experience alongside the way.
- Plaster files.
These are TOML files, even though they look pretty similar to ini files.
Each `[[substitution]]` entry represents an individual regex operation to be
applied to a file. The format for plasters is something like this
```toml
[[substitution]]
description = ''
re_pattern = ''
replace = ''
re_flags = ''
count = 0
```
A user can list as many of these entries as necessary for each regex
that one desires to apply to a given source.
