Also, another good command for getting differences is diff.  It is more
flexible and can recurse into externals.  It can also compare against
on-disk copies that are not from subversion, such as comparing against

svn co https://svnemc.ncep.noaa.gov/projects/nems/
branches/WAM-IPE_NEMS201606/src/module_MEDIATOR_SpaceWeather.F90 at 90097 old
svn co https://svnemc.ncep.noaa.gov/projects/nems/
branches/WAM-IPE/quasitrunk/src/module_MEDIATOR_SpaceWeather.F90 new

diff -rU3 -x.svn old new > my.diff


svn co https://... old = check out this branch in a directory called "old"
  -r = recurse into subdirectories
  U3 = universal format diff with three lines of context (same format as
svn diff)
  -x.svn = do not walk into subversion metadata directories
  old new = diff the two directories

Another useful option is -w which ignores differences in whitespace.

  diff -rwU3 old new > my.diff
