+ * The ril_config_merge_files() function does the following:

+ * 1. Loads the specified key file (say, "/etc/foo.conf")
+ * 2. Scans the subdirectory named after the file (e.g. "/etc/foo.d/")
+ *    for the files with the same suffix as the main file (e.g. "*.conf")
+ * 3. Sorts the files from the subdirectory (alphabetically)
+ * 4. Merges the contents of the additional files with the main file
+ *    according to their sort order.
+ *
+ * When the entries are merged, keys and groups overwrite the exising
+ * ones by default. Keys can be suffixed with special characters to
+ * remove or modify the existing entries instead:
+ *
+ * ':' Sets the (default) value if the key is missing
+ * '+' Appends values to the string list
+ * '?' Appends only new (non-existent) values to the string list
+ * '-' Removes the values from the string list
+ *
+ * Both keys and groups can be prefixed with '!' to remove the entire key
+ * or group.
+ *
+ * For example if we merge these two files:
+ *
+ *   /etc/foo.conf:
+ *
+ *   [foo]
+ *   a=1
+ *   b=2,3
