Include parameter is used for including a file, the file must be readable.
Include parameter is used for including a directory:
- All files in the directory must be readable. - No particular order of inclusion should be assumed (e.g. files are not included in alphabetical order). Therefore do not define one parameter in several ''Include'' files (e.g. to override a general setting with a specific one). - All files in the directory are included into configuration. - Beware of file backup copies automatically created by some text editors. For example, if editing the ''include/my_specific.conf'' file produces a backup copy ''include/my_specific_conf.BAK'' then both files will be included. Move ''include/my_specific.conf.BAK'' out of the "Include" directory. On Linux, contents of the ''Include'' directory can be checked with a ''ls -al'' command for unnecessary files.
