  SELinux policy files with definitions of file contexts:
    - Labeling Policy Files: *.fc
    - Policy Config. Files: file_contexts, file_contexts_*, file_contexts.local,
        file_contexts.homedirs, file_contexts.template, homedir_template
    - SE for Android Policy Config. Files: service_contexts, property_contexts,
        hwservice_contexts
    - Policy Build Files: initial_sid_contexts, genfs_contexts, fs_use

  Change log:
   * Version 5 [03-Oct-2019]: Replace unnecessary WordDetect rules.
   * Version 4 [02-Apr-2019]: Remove one indentation.
   * Version 3 [09-Sep-2018]:
      - Update itemData's style for the new Solarized color schemes.
   * Version 2 [28-Aug-2018]:
      - Some improvements. RegExp and some rules are moved to "selinux.xml".
      - Add statements keywords that use file contexts.
   * Version 1 [26-Jan-2018, by Nibaldo González]:
      - Initial version.
