# ansible_lib: al_include_os_vars_path
#
# Description: Include OS specific variables from al_os_vars_path
#
# Input:
#
#   al_os_vars_path ................ directory to read variables from
#
# Output: none
#
# Example:
#
#   vars:
#     al_os_vars_path: "{{ playbook_dir }}"
#   tasks:
#     - include_role:
#         name: vbotka.ansible_lib
#         tasks_from: al_include_os_vars_path.yml
#
# Notes:
#
#   1) Create files vars/defaults/default.yml and vars/default.yml (at
#      least empty).
#   2) Variables in vars/defaults/* will be overwritten by the file from
#      "with_first_found" in vars.
#   3) Variables in vars/main.yml will be overwritten by the file from
#      the list "with_first_found".
