[kepler-dev] Combined commandline and exec actors

[Bertram Ludaescher]

Ilkay:

Nice that those have been merged (or rather their functionality).
BTW, what were the main differences of the two? (Sorry, I think that
might have been discussed before).  I guess merging made sense since
each actor had something useful that the other didn't have (in
addition to sparing the user to think about which of two very similar
actors to use).


All: 

I assume that once the new KSW files are in place, together with the
object manager (a better name than cache manager, right?) then
updating of workflows is no longer needed!? 
Legacy workflows can continue to use "old" actors ad infinitum and all
of this will be automatic, transparent, easy going..

Chad, Matt, Ilkay et al: 

Aproposa KSW: I realize that the extension KAR is already used. But
who cares. I think the advantages over KSW outweigh the (probably
non-critical) issue of "some other program uses that extension" (KAR
correctly connotates *AR*chival files such as TAR and JAR; also it's
pronouncable unlike KSW).
