# By default all command-line options are passed to `svn update` or `hg/git
|
|
# pull` in addition to $UPDATE_OPTIONS (defined below). If the first parameter

|
# reads --nostdflags, $UPDATE_OPTIONS as well as this parameter itself

# are omitted.
|
|
#
|
|
# If the first parameter reads --patch, the second parameter is considered
|
|
# a patch file.
|
|
#
|
|
# 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# only generated files that appear to be out of date in the local tree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

# their dependencies will be printed; --help prints this message.
|

|
|
# If the first parameter is --silent, this script prints nothing other
|

# than error messages; the second parameter is then interpreted as above.
