Transient optiton

[trailway]

I have written a custom action which takes an input file and then determines whether or not to rebuild an output file based on file dates. It takes a number of options and works well.

What I want to be able to do is to rebuild the output if the user indicates that they wish to ignore the file dates and just do it. The odd thing about my request is that I do not want this option to be persistent, i.e. it should be a one shot deal. I am afraid that a user might leave the option and would like to eliminate that option.

Any suggestions?
