Dev:Substitute

(lib)substitute
Substitute is a system for modifying code at runtime by substituting custom implementations for arbitrary functions and Objective-C methods. It is also a Free Software (& open-source) substitute for Cydia Substrate.

The library is used in the Electra jailbreak.

Substitute was originally made by comex on 2015, but CoolStar has since taken over the project sometime in 2018.
