DESCRIPTION

66       This module provides an object that read and write annotations (a bit
67       like comments) to and from a configuration tree and save them in a file
68       (not configuration file). This module can be used to save annotation
69       for configuration files that do not support comments.
70
71       THis module should not be used for configuration files that support
72       comments.
73
74       Depending on the effective id of the process, the annotation is saved
75       in:
76
77       ·   "/var/lib/config-model/<model_name>-note.yml" for root (EUID == 0)
78
79       ·   "~/.config-model/<model_name>-note.yml" for normal user (EUID > 0)
80

CONSTRUCTOR

82       Quite standard. The constructor is passed a Config::Model::Instance
83       object.
