When you enter './config.status --help' at the command line, you get:
$ ./config.status --help
`config.status' instantiates files from templates according to the
current configuration.
Usage: ./config.status [OPTION]... [FILE]...
...
The 'Usage' line above should read:
Usage: ./config.status [OPTION]... [TAG]...
in order to be consistent with the documentation in the manual. The use
of file in this location can also be somewhat confusing relative to
other uses of the term FILE in this same help text. For example, in the
--file and --header options:
...
--file=FILE[:TEMPLATE]
instantiate the configuration file FILE
--header=FILE[:TEMPLATE]
instantiate the configuration header FILE
...
A user might confuse the use of FILE in the Usage line with the use of
FILE in these options.
