*snip shell script*

When I am building or installing a kernel and/or world, I use a shell 
script[1] I wrote awhile back.  It could be better ("automatic" option 
probably does not work and should be removed), but it makes building and 
installing easier for me.

I wonder how many build scripts have been written over the years.
