#> Build a Gemini site
#>
#> This Makefile manages the building and publishing of the Gemini site:
#>   1. Delegating content directories to other makefiles
#>   2. Building the site index page
#>   3. Copying the site to the hosting location
#>
#> Run `make -f environment.mk show' to display the key global varibles.
