7 # By default all command-line options are passed to `cvs update` in
8 # addition to $UPDATE_OPTIONS (defined below). If the first parameter
9 # reads --nostdflags, $UPDATE_OPTIONS as well as this parameter itself
12 # If the first parameter reads --patch, the second parameter is considered
15 # If the first parameter is --touch, no cvs operation will be performed,
16 # only generated files that appear to be out of date in the local tree
19 # If the first parameter is --list, a list of the generated files and
20 # their dependencies will be printed; --help prints this message.
