-  Add/remove option to the option file section.
-
-  SYNOPSYS
-    modify_defaults_file()
-    file_location     The location of configuration file to edit
-    option            The name of the option to look for (can be NULL)
-    option value      The value of the option we would like to set (can be NULL)
-    section_name      The name of the section (must be NOT NULL)
-    remove_option     This defines what we want to remove:
-                        - MY_REMOVE_NONE -- nothing to remove;
-                        - MY_REMOVE_OPTION -- remove the specified option;
-                        - MY_REMOVE_SECTION -- remove the specified section;
-  IMPLEMENTATION
-    We open the option file first, then read the file line-by-line,
-    looking for the section we need. At the same time we put these lines
-    into a buffer. Then we look for the option within this section and
-    change/remove it. In the end we get a buffer with modified version of the
-    file. Then we write it to the file, truncate it if needed and close it.
-    Note that there is a small time gap, when the file is incomplete,
-    and this theoretically might introduce a problem.
