- *
- * VIM - Vi IMproved by Bram Moolenaar
- *
- * Do ":help uganda" in Vim to read copying and usage conditions.
- * Do ":help credits" in Vim to see a list of people who contributed.

- /*
- * Code to handle user-settable options. This is all pretty much table-
- * driven. Checklist for adding a new option:
- * - Put it in the options array below (copy an existing entry).
- * - For a global option: Add a variable for it in option.h.
- * - For a buffer or window local option:
- * - Add a PV_XX entry to the enum below.
- * - Add a variable to the window or buffer struct in structs.h.
- * - For a window option, add some code to win_copy_options().
- * - For a buffer option, add some code to buf_copy_options().
- * - For a buffer string option, add code to check_buf_options().
- * - If it's a numeric option, add any necessary bounds checks to do_set().
- * - If it's a list of flags, add some code in do_set(), search for WW_ALL.
- * - When adding an option with expansion (P_EXPAND), but with a different
- * default for Vi and Vim (no P_VI_DEF), add some code at VIMEXP.
- * - Add documentation! One line in doc/help.txt, full description in
- * options.txt, and any other related places.
