Glyphs for Examples
===================
In Texinfo, code is often illustrated in examples that are delimited
by `@example' and `@end example', or by `@lisp' and `@end lisp'. In
such examples, you can indicate the results of evaluation or an
expansion using `=>' or `==>'. Likewise, there are commands to insert
glyphs to indicate printed output, error messages, equivalence of
expressions, and the location of point.
The glyph-insertion commands do not need to be used within an
example, but most often they are. Every glyph-insertion command is
followed by a pair of left- and right-hand braces.
