A script that downloads a template from one of my formulae and saves it to disk as a new file. A starting point for whatever I need to build.
To instantiate my shell script template, I run it like this:
instantiate template.sh newscript.sh
To instantiate my Python commandline script template, I run it like this:
instantiate cli.template.py newscript.py
The script itself is nice and simple (and, of course, based on my shell script formula).
