Using Makefile to run guix shell?

[Peter Polidoro <peter@polidoro.io>]

In the root of every project directory, I now include a 
channels.scm file and a manifest.scm file.

I was using direnv to automatically launch guix shell, but I 
wanted more flexibility to easily launch variations of guix shell.

Now I am also including a Makefile in the root of every project 
directory so I can use "make guix-shell" or "make guix-container" 
or "make project-documentation" etc to quickly run commands.

This works well for certain types of projects, but there could be 
conflicts with projects that expect or automatically generate 
their own Makefiles.

I could use a different Makefile name for my guix commands, but 
that makes my commands less convenient to type.

Is it considered bad practice to use make like this? Is there a 
better way to do something similar?
