# WriteFreely CSS invalidation script

# usage: ./invalidate-css.sh <build-directory>

# This script provides an automated way to invalidate stylesheets cached in the

# browser. It uses the last git commit hashes of the most frequently modified

# LESS files in the project and appends them to the stylesheet `href` in all

# template files.

# This is designed to be used when building a WriteFreely release.

# Get parent build directory from first argument

# Get short hash of each primary LESS file's last commit
