A reasonably generic framework for applying arbitrary hex-level edits to files
This is a library/framework used for creating "patches" to binary files. Ultimately, it's just a way of defining, loading and applying any number of byte-level modifications to a binary file. It uses ModEngine as its underlying framework and includes a HexPatchEngine that can be used with ModEngine to quickly drop-in HexPatch functionality.
HexPatch was originally designed for, and is likely most applicable to, scenarios like game modding where manual hex edits to binary files can be hard to track, easy to get wrong and often impossible to combine.
This project also includes HexPatch.Build, an additional companion library for HexPatch that uses BuildEngine to simplify semi-isolated repeatable environments for these edits. You should consider this deprecated in favour of ModEngine.Build.
