----- HyperTalk script -----
-- Thanks to Pat Lynch's public domain Bird Anatomy for the layout
-- of a few top level cards. The scripts are completely rewritten.
-- We try to avoid button and field scripts. To make the functionality
-- more uniform, mostly the title of buttons and fields is used to
-- indicate what they are supposed to do and here we interpret
-- the action according to what type and object is selected.
-- This gives the whole hierarchy more of a class oriented rather
-- than prototype oriented look and avoids tons of duplicated small
-- scripts.
-- See the HELP CARD for more info on how this works.
--
-- This script also contains some supporting functions that
-- are only useful in develping new stacks functioning this way.
-- Perhaps they are useful to others too. You have to call them
-- from the message window.
--
--                   Enjoy,
--                       Heinz

-- Import / Export
-- This is a simple facility only, we do not attempt to get a
-- complete ASCII equivalent of a stack.
-- Field text is filled from a file into card fields
-- that are known already in the stack.
-- The syntax for import/export is this:
-- CARD: CardName
--       makes CardName the card to copy whenever a new card is
--       requested subsequently.
-- :END:
--        terminates the file
-- FieldName: MultiLineText
--        enters a multi line text into the field called FieldName.
--        If the fieldname is "Name", then a new card is created
--        by copying the current card called CardName.
-- :: comment
-- __ comment
--        starts a comment line.
