-* Name:
-* ast_test
-
-* Purpose:
-* Test installation of the AST library.
-
-* Type:
-* C program.
-
-* Description:
-* This program performs a simple test (without using graphics) of
-* the AST library, to check that it is correctly installed. It is
-* not an exhaustive test of the system.
-
-* Arguments:
-* None.
