+# By default all command-line options are passed to `svn update` in
# addition to $UPDATE_OPTIONS (defined below). If the first parameter

# If the first parameter reads --patch, the second parameter is considered
# a patch file.

-# If the first parameter is --touch, no cvs operation will be performed,
+# If the first parameter is --touch, no svn operation will be performed,
# only generated files that appear to be out of date in the local tree
# will be touched.
#
# If the first parameter is --list, a list of the generated files and

#
+# If the first parameter is --silent, this script prints nothing other
+# than error messages; the second parameter is then interpreted as above.
