I'm not sure I'm using the right terms. Long ago I tinkered with Eclipse and recall there were "environment variables" that could be specified in project settings and compiler directive fields in the GUI itself to customize builds. I believe the syntax was similar to ant properties, like ${env.HOME} for inserting the user's home directory path into some field.
Are similar variables accessible to FlashBuilder? I've been searching and can't find a list or documentation about such (not saying it doesn't exist, I just haven't found it yet). Basically, I want to pass several variables into the "Additional compiler arguments", like user name, FlashBuilder version, date time, and anything else from the list of variables that might be accessible and interesting.
