This script is used to automatically fix issues within xml documentation
files.
The script is *for now* intended to be used ad-hoc, and the commits to
be examined.
A future discussion will define whether:
* This commit and scripts are kept.
* The script is extended for common use.
The biggest issue right now with the script is that it *could* in theory
destroy a valid space-less varlistentry.
The script could, in practical use, be changed and extended to normalize
some parts of the XML files, mainly:
* A common quoting style for attributes
* Fix-up some weird formatting automatically that xmlformat doesn't

# This script is written intended as a living, evolving tooling
|
|
# to fix oopsies within the docbook documentation.

|
|
# This is *not* a formatter. It, instead, handles some known cases
|
|
# where something bad happened, and fixing it manually is tedious.

|
|
# Read the code to see the different cases it handles.
|
|
#
|
|
# ALWAYS `make format` after fixing with this!
|
|
# ALWAYS read the changes, this tool isn't yet proven to be always right.
