esplugin

A free software library for reading Elder Scrolls Plugin (.esp), Elder Scrolls Master (.esm) and Elder Scrolls Light (.esl) files. It can currently parse plugins for the following games:

• TES III: Morrowind
• TES IV: Oblivion
• TES V: Skyrim (including Special Edition)
• Fallout 3
• Fallout: New Vegas
• Fallout 4

esplugin is a rewrite of libespm and focuses on providing a useful API to libloadorder and LOOT, rather than a general-purpose plugin parser.
