Problem/Motivation
Site builders often look for an easy way to create a theme, and sub-theming is a great solution, for example based on Bootstrap.
Proposed resolution
It would be nice if a sub-theme based on the new default Drupal front-end theme Olivero could be easily created from the command line, by adding a sub-theme folder in the Olivero theme, to use as a template for sub-theme generation.
API changes
New command for generating an Olivero sub-theme:
core/scripts/create-subtheme.sh my_theme
