- Add notes folder with MDBook documentation (the NOTES.md file was getting kind of large) - Add rz_analyze.py, does the same a r2_analyze.py just with Rizin instead of radare2 so the project can be loaded in Cutter (*and* it's faster) - Add Scrap.rzdb, Rizin database for the Scrap.exe executable - Add Scrapper_rs, Rust version of .packed extractor and repacker - replace helplib.txt with helplib.md - add Py_Docs folder which contains generated documentation for the binary python modules built into Scrap.exe
