[Swift-devel] Re: swift-falkon problem

[Ioan Raicu]

What does the last option "swift" really do?  Is that the chdir?  If 
yes, then it should be a default behavior (rather than an option) as 
long as the directory field is specified.  Do you have SVN permissions 
to commit changes?  If yes, you should commit this.  If not, I'll commit 
it, and you need to get the permissions to commit code to the Falkon SVN 
(I'll work on this).
