This repository contains a number of Python scripts that can be imported into LLDB. Some of them are specific to Manticore (manticore.cs.uchicago.edu), but should be able to be easily modified to suit other projects.
You can import all scripts within a file by default by creating a ".lldbinit" file in your home directory, that contains the following line:
command script import <path to commands.py>/commands.py
