List of available targets

Here is how to get the list of available targets in the ECF file project.ecf:

	gedoc --format=available_targets project.ecf

This will display to the standard output (console window) the list of targets in the order found in the ECF file project.ecf.

Checking that a target is available

It is also possible to check whether a given target exists in an ECF file:

gedoc --format=available_targets --target=foo project.ecf

In addition to displaying the list of targets found in the ECF file project.ecf, the command will exit with a non-zero exit code if the target foo does not exist. This can be used in combination with the option --silent in a script in order to determine what ECF target to use before invoking the Eiffel compiler.
