options:

    description:
    - Determine whether symbolic links should be followed.
    - When set to V(true) symbolic links will be followed, if they exist.
    - When set to V(false) symbolic links will not be followed.
    - Previous to Ansible 2.4, this was hardcoded as V(true).
    type: bool
    default: no
    version_added: '2.4'
notes:
- For Windows you can use M(ansible.windows.win_template) which uses V(\\r\\n) as O(newline_sequence) by default.
- The C(jinja2_native) setting has no effect. Native types are never used in the M(ansible.builtin.template) module
  which is by design used for generating text files. For working with templates and utilizing Jinja2 native types see
  the O(ansible.builtin.template#lookup:jinja2_native) parameter of the P(ansible.builtin.template#lookup) lookup.
