* Obvious Warning

This code contains spoilers! If you haven't played _Dreamhold_, and you
read this code, you'll certainly ruin the game for yourself. Play it
first. I am releasing this code for the benefit of Inform programmers
who are familiar with _Dreamhold_ and want to know how I did it.

* About The Source

This code is exactly the version I used to build _Dreamhold_ release
5. I have not added explanatory comments; you're on your own for this
safari.

main.inf is the top-level source file; it includes all the others.

The package includes a modified version of the Inform 6/10 library.
_Dreamhold_ must be built with this version. The modifications are
tagged with "--Z" comments. A quick overview of the changes:

- The AMERICAN_COMMAS option tells the library to use the serial comma
  for lists.

- The SKIP_MAGIC_ARTICLES option turns off Inform's ability to
  auto-detect whether "a" or "an" is appropriate for object names.
  (Objects are defined with explicit article properties where
  necessary.) This makes the game run very slightly faster.

- The USE_PARTINVENT option allows the list writer to use a
  "partinvent" property. This works like "invent", except that it
  works for lists when PARTINV_BIT is set (instead of FULLINV_BIT).
  This lets me adjust objects in room listings just the way "invent"
  lets me adjust them in inventory listings.

- The INTERRUPT_MULTI_ACTION option allows game code to interrupt
  a multiple-object action (like "take all" or "put all in box".)

- The ALLOW_AFTERGAME_RETRY option allows a post-game option (like
  "amusing") to return the player to life. (Dreamhold does not make
  use of this option.)

* To Compile

The game was developed with Inform 6.21. It can be compiled with the
latest Inform 6 release (6.33), although you'll see a couple of
compilation warnings.

The compile command (type all on one line):

inform -~D -~S -v8 +include_path=,lib610 
   '$huge' '$MAX_PROP_TABLE_SIZE=25000' '$MAX_OBJECTS=700' 
   main.inf dreamhold.z8
