A shell script to generate a CSS file with @font-face declarations for web fonts in a given directory.

Run the script with the following options:

• -d, --directory: The directory containing the web fonts. Default is the current directory.
• -o, --output: The name of the output CSS file. Default is "fonts.css".
• -e, --exclude: A directory to exclude from the search.

For example:

./ff2ff.sh -d /path/to/fonts -o my-fonts.css -e /path/to/fonts/excluded-directory

The script sorts @font-face declarations alphabetically by font family name.
