Full Changelog: v0.8.0...v0.8.1

We're proud to announce the first versioned release of Chisel!

Work has been ongoing for the last few months, and this release represents the first of many upcoming releases.

Chisel is a software tool for carving and cutting Debian packages!

It is built on the idea of package slices - minimal, complimentary and loosely coupled sets of files, based on the package’s metadata and content. Slices are basically subsets of the Debian packages, with their own content and set of dependencies to other internal and external slices.

To install the latest version of Chisel, run the following command:

go install github.com/canonical/chisel/cmd/chisel@v0.8.0

Chisel is invoked using chisel . To get more information:

To see a help summary, type chisel -h.
To see a short description of all commands, type chisel help --all.
To see details for one command, type chisel help <command> or chisel <command> -h.
