The new option -D<name>=<value> allows you to defined a value on the eclcc command line that can be accessed from the ECL.

The name is the fully qualified name of the attribute that is being defined. Value is the text of the attribute.

e.g.,

import ^ as repo;
output(repo.optionXX);
all in that bug
if you compile

eclcc "-DoptionXXX='hello'"

it will be equivalent to

output('hello');
