diff.py:
let's try to use AI in a smarter way:
- run current and proposals from openai, copilote, mistralai, gemnicodeworks
- compare results (accept slight massage at interface naming, output must be same as original)
- compiles without hurting much interface: openai,, gemini
- don't crash and result ok: openai,
- crash and burn : gemini, mistralai
- change interface (remove a parameter): copilote
- lines_of_code (ignoring commente of gemini): original: 170 , openai: 129, copilote: 98, mistralai: 161, gemini: 350

in the end, still 1 day to:
- digest the AI change
- then do the re-engineering to move diff.py down

package_index_markdown (try on copilote, as move of code between the project files)

i would like to have the core part of the "package_index_markdown" function pushed from make.py down to wppm.py. 
Goal is to have less things in make.py, and more in wppm.py so most of the feature is available from wppm 

proposed the stupid/basic solution, good here

adding safe exit to llm , "do you think it's possible ? is there enough information to", may reduce allucinations

to copilote:
could we make piptree working either on current installeed packages, either in a directory of packages ? it seemes all we need is reading the metadata from the archive like wheelhouse.py does

gives a general structure that works, but prefer doing integration by hand so far

asking an AI (copilote github) to take care not disrupting existing code... does work!

I would like the diff.py program to be usable to compare  two given markdown files, currently it's doing it's own scanning of directory... can you help rework it so it can do current feature and new one ? ````
