 Tool to customise a Raspbian image by mounting it as a loop device and running commands in it with *chroot* and *qemu*. This enables automated creation of the customised Rasbian images, and is designed to use in CI/CD pipelines to package software into a pre-configured image which can easily be deployed to a Raspberry Pi.
