In what little testing I've done, it looks like, if I have to publish multiple scripts, I have to do it once for each one. Our development scripts are structured in a psuedo-object-oriented fashion. It would be convenient then to take a directory, or a group of files and publish them to IOS all at once.

But Link is extensible through REBOL, correct? So if REBOL can, I assume we can create an app in Link to do so.

I mean, within Link, using REBOL, can I intercept a change in a file and us it to fire of an action. It is functionality that we could use to help us manage our scripting process. -- Sincerely, | Cold Hearted Orb, that rules the night. Removes Ed Dana | the colours from our sight!
