The example below shows a schema on the left and what you
need to say to get it on the right.
#example10#
The command 1 (read `Such That') is the same as the previously used
command 2 which has been kept as an alias for upward compatibility.
If you want a schema with no name, just a horizontal rule at the top,
use the 3 environment instead.
You can set various parameters (see Section 7) to change the box style,
for example:
#example19#
Schemas can also be defined using a horizontal notation, for example:
#example28#
A generic schema is produced as follows.
#example33#
