-/* A Short Introduction to Adding a Command-Line Option.
-
- Before adding a command-line option, consider if it is really
- necessary. Each additional command-line option adds complexity and
- is difficult to remove in subsequent versions.
-
- In the following, consider adding the command-line argument
- `--bar'.
-
- 1. Each command-line option is specified in the specs file. The
- notation is described below in the comment entitled "The Specs
- Language". Read it.
-
- 2. In this file, add an entry to "option_map" equating the long
- `--' argument version and any shorter, single letter version. Read
- the comments in the declaration of "struct option_map" for an
- explanation. Do not omit the first `-'.
-
- 3. Look in the "specs" file to determine which program or option
- list should be given the argument, e.g., "cc1_options". Add the
- appropriate syntax for the shorter option version to the
- corresponding "const char *" entry in this file. Omit the first
- `-' from the option. For example, use `-bar', rather than `--bar'.
-
- 4. If the argument takes an argument, e.g., `--baz argument1',
- modify either DEFAULT_SWITCH_TAKES_ARG or
- DEFAULT_WORD_SWITCH_TAKES_ARG in gcc.h. Omit the first `-'
- from `--baz'.
-
- 5. Document the option in this file's display_help(). If the
- option is passed to a subprogram, modify its corresponding
- function, e.g., cppinit.c:print_help() or toplev.c:display_help(),
- instead.
-
- 6. Compile and test. Make sure that your new specs file is being
- read. For example, use a debugger to investigate the value of
- "specs_file" in main(). */
