Sure, but that only works if you think about it before launching it. And I only 
know `screen` as a utility to run multiple commands/sessions from a single 
shell, a more advanced for of the Ctrl-Z, bg and fg shell commands. What I'm 
thinking about is phoning in from anywhere and peek at the logfile through a 
filter that detects the `:info:[^ ]* [X/Y] .*` from the possibly interminable 
compiler commands in that file and presents them in an easy to digest fashion.

My initial idea was to roll my own, and then I realised the code to do this 
exists and that it might be possible to write a Tcl script that reuses that 
code. Heck, maybe it's even an idea to implement something like a `port state 
foo` command that prints the currently executing phase for port:foo and the 
current progress if that information is available.
