Hey thanks! This fits my needs nicely. I'm having problems with variable $cower_dl_dir/ in line 44 however. When I run the script it turns up blank (a scoping issue?) and so the script tries to cd in $HOME (I think) rather than my "Builds" folder.

I've hard-coded the correct path to my "Builds" folder at that point (in place of the variable) and the script works as expected. I have set my TargetDir in cower's config.
