0-b     Options and how to set them.

A quick way to make small changes to the options, without having to
switch to a different option file, is to use the command line options
-extra-opt-first or -extra-opt-last, which make it as if the given
option was (repsecitvely) at the top or bottom of the option file.  For
example,
    -extra-opt-last wiz_mode=yes
will cause any new game to start in wizard mode.  -extra-opt-first and
-extra-opt-last can be used multiple times on the same command line.

Examples:

Example:

Options can be rerefenced by lua via "options.option_name".  For
example:
:if string.find(options.autopickup, "!") then
# Do something here if potions are included in autopickup
:end
"options.option_name" can even be used for options that crawl itself
doesn't recognize.  This can be combined with setting options on the
command line (see section 0-b) to use the command line to control
conditionalization of options in the options files.  For example, on the
command line you could set the option "foobar" with "-extra-opt-first
foobar=true", and then do:
:if options.foobar then
# Do things here
:end
7-c     Conditional option caveats.
-----------------------------------

The above caveat applies to the "wiz_mode" option as well.

The above caveat applies to the "wiz_mode" option as well.  Instead of
conditionalized wiz_mode, you can add to the command line
"-extra-opt-last wiz_mode=yes" to make any new game start in wizard
mode.
