alias sb='cd ~/images/functions; 
          bldir=`date +%Y/%m/%d`; 
          mkdir -p $bldir; 
          cd $bldir; 
          ln -s ~/bin/blot-glut ./blot; 

This alias makes a sym-link, to the Blot executable, in the current directory as a workaround to a bug (perhaps the macosx GLUT library) that sets the working directory for the blot session to the directory the binary is sitting in, rather than the directory that Blot was started from. Under cygwin or linux, I usually remove the 'ln -s' line.
