This is the "Christmas Tree Demo"; it has one of everything.  It produces some
quaint little files in your home directory.  Here's what I got when I ran it:

thud> ls ~/file*
/pearl/homes/battle/file0       /pearl/homes/battle/file4
/pearl/homes/battle/file2       /pearl/homes/battle/file6
thud> more ~/file*
