constructor is a tool which allows constructing an installer for a collection of conda packages. Basically, it creates an Anaconda-like installer consisting of conda packages. This tool was previously proprietary and known as cas-installer.

As of version 1.3.0, constructor may be installed into any conda environment using:

$ conda install constructor

Once installed, the constructor command will be available:

$ constructor -h

The constructor command takes an installer specification directory as its argument. This directory needs to contain a file construct.yaml, which specifies the name of the installer, the conda channels to pull packages from, the conda packages included in the installer etc. . The complete list of keys in this file can be found in CONSTRUCT.md. Also, the directory may contain some additional optional files (such as a license file, and image files for the Windows installer). An example is located in examples/maxiconda.

• Constructor does not work with noarch-Python packages, all conda packages must be available for the platform you are building the installer for.
