7-a     Executing lua.
----------------------
Lua code can be used directly in your init.txt/.crawlrc. You can
execute Lua code using the following syntax.
: Single line of lua code

Lua code can be used directly in your init.txt/.crawlrc. You can use Lua
to selectively include parts of your init.txt (based on character type, 
for instance) using this syntax:

< Possibly multi-line
  Lua code >

< Lua code >
or
<
Lua code
>
or
: Lua code till end of line

{ Possibly multi-line 
  Lua code }
In the second and third cases, the restriction is that the delimiter
characters appear at the beginning and end of a line, respectively.
The difference between the <> and {} is when the code gets executed.
Code {}, it is executed right away.  Other Lua code is executed only 
after the entire init file is read in.

# Another welcome message

# Controlling visibility of options:

You can use Lua to selectively include parts of your init.txt (based
on character type, for instance) using the same syntax.
Examples:

7-c     Including external files.
---------------------------------
You can use Lua to include options from other files. This is actually
just a particularly useful way to use the previously discussed features.
Example:
# Set the monster glyphs back to the way they were in 0.3.4
: crawl.read_options('docs/monsters_034.rc')

If you don't like the standard keyset (either because some keys do not 
work properly, or because you want to decrease the amount of typing 
necessary), you can use keymaps and macros. See macro.txt in the Docs 
directory, or read it from the in-game help menu.
