Description:
    Generates a configuration class for database snapshots.

Example:
    rails generate snapshot NAME [options]

    This will create:
        - A new snapshot configuration file at db/snapshots/YYYYMMDDHHMMSS_NAME.rb

Options:
    --exclude_tables=one two three
        This option allows you to specify tables that should be excluded from the snapshot.
        You can list multiple tables by separating them with a space.

        Example:
            rails generate snapshot MySnapshot --exclude_tables=users sessions logs

        This will generate a configuration file that excludes the 'users', 'sessions', and 'logs' tables.

More Information:
    The generated configuration file is a Ruby class that extends ActiveRecord::DbSnapshot.
    You can edit this class to further customize the behavior of your database snapshot.
