[Lunar-commits] <lunar> Progressbar/spinner for compile logs.

[Auke Kok]

commit 7aa8920c328586ec8555a48e64324580c940f6e9
Author: Auke Kok <sofar at foo-projects.org>
Date:   Tue Jun 14 22:36:11 2011 -0700

    Progressbar/spinner for compile logs.
    
    Enable the spinner as follows:
    
    	# lunar set VOYEUR pc
    
    The spinner works as follows:
    - estimates the compile progress based on the length of the previous compile log
    - paints a progress bar with % number
    - if no previous compile log found, displays a spinner!
