# Mark C. Miller, Wed Mar 11 10:03:10 PDT 2009
61
# Added browserOptsDef and set lowlevel to 0. That is important when
62
# diff'ing HDF5 files.

# Mark C. Miller, Wed Dec 2 11:47:31 PST 2009
65
# Added logic to use path to browser that is 'next to' silodiff or fall
66
# back what a browser in path, but issue a warning if they are somehow
69
# Mark C. Miller, Fri Dec 4 09:58:17 PST 2009
70
# Made it possible to override browser path warning
