-/**
- * 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
- *   c=4
- *   d=5
- *   [bar]
- *   e=5
- *
- *   /etc/foo.d/bar.conf:
- *
- *   [foo]
- *   a+=2
- *   b-=2
- *   c=5
- *   !d
- *   [!bar]
- *
- * we end up with this:
- *
- *   [foo]
- *   a=1
- *   b=2,3
- *   c=5
- *
- * Not that the list separator is assumed to be ',' (rather than default ';').
- * The keyfile passed to ril_config_merge_files() should use the same list
- * separator, because the default values are copied from the config files
- * as is.
