+ * will appear in that style. For a memory stream, style changes have no effect.
+ * For a file stream, if the machine supports styled text files, the styles may
+ * be written to the file; more likely the style changes will have no effect.
+ *
+ * Styles are exclusive. A character is shown with exactly one style, not a
+ * subset of the possible styles.
+ *
+ *
+ * Note that every stream and window has its own idea of the current
+ * style. Sending a style command to one window or stream does not
+ * affect any others.
+ *
+ *
+ * Except for a window's echo stream; see Echo Streams.
+ *
+ *
+ * The styles are intended to distinguish meaning and use, not formatting. There
+ * is no standard definition of what each style will look like. That is left up
+ * to the Glk library, which will choose an appearance appropriate for the
+ * platform's interface and the player's preferences.
+ *
+ * There are currently eleven styles defined. More may be defined in the future.
+ *
+ * Styles may be distinguished on screen by font, size, color, indentation,
+ * justification, and other attributes. Note that some attributes (notably
+ * justification and indentation) apply to entire paragraphs. If possible and
+ * relevant, you should apply a style to an entire paragraph — call
+ * glk_set_style() immediately after printing the newline at the beginning of
+ * the text, and do the same at the end.
+ *
+ *
+ * For example, %style_Header may well be centered text. If you print
+ * Welcome to Victim (a short interactive mystery), and only the
+ * word Victim is in the %style_Header, the center-justification
+ * attribute will be lost. Similarly, a block quote is usually indented on both
+ * sides, but indentation is only meaningful when applied to an entire line or
+ * paragraph, so block quotes should take up an entire paragraph. Contrariwise,
+ * %style_Emphasized need not be used on an entire paragraph. It is often used
+ * for single emphasized words in normal text, so you can expect that it will
+ * appear properly that way; it will be displayed in italics or underlining,
+ * not center-justified or indented.

+ *
+ * Initially, no hints are set for any window type or style. Note that having no
+ * hint set is not the same as setting a hint with value 0.
+ *
+ * These functions do not affect

+ * create subsequently. If you want to set hints for all your game windows, call
+ * glk_stylehint_set() before you start creating windows. If you want different
+ * hints for different windows, change the hints before creating each window.
+ *
+ *
+ * This policy makes life easier for the interpreter. It knows everything about
+ * a particular window's appearance when the window is created, and it doesn't
+ * have to change it while the window exists.
+ *
+ *
+ * Hints are hints. The interpreter may ignore them, or give the player a choice
+ * about whether to accept them. Also, it is never necessary to set hints. You
+ * don't have to suggest that %style_Preformatted be fixed-width, or
+ * %style_Emphasized be boldface or italic; they will have appropriate defaults.
+ * Hints are for situations when you want to change the
+ * appearance of a style from what it would ordinarily be. The most common case
+ * when this is appropriate is for the styles %style_User1 and %style_User2.
+ *
+ * There are currently ten style hints defined. More may be defined in the

+ *
+ * Again, when passing a style hint to a Glk function, any value is actually
