verifycommand – Verifies definitions are unchanged, such as before patching
This package is intended for package authors who patch code from other packages.
To improve reliability, the verifycommand package provides a way to verify that macros or environments have not changed. This allows a package author to check before patching a definition. If a definition is not as expected, a warning is issued. At the end of the compile, a list of all changed definitions is displayed.
