This command should be used when building programs which use the AST
library, in order to generate the correct arguments to allow the compiler
to link your program. The arguments generated are written to standard
output but may be substituted into the compiler command line in the
standard UNIX way using backward quotes (see below).
By default, it is assumed that you are building a stand-alone program
which does not produce graphical output. However, switches are provided
for linking other types of program.
