All commands (except help) require a tracker specifier. This is just
the path to the roundup tracker you're working with. A roundup tracker
is where roundup keeps the database and configuration file that defines
an issue tracker. It may be thought of as the issue tracker's "home
directory". It may be specified in the environment variable TRACKER_HOME
or on the command line as "-i tracker".

A designator is a classname and a nodeid concatenated, eg. bug1, user10, ...

Property values are represented as strings in command arguments and in the
printed results:
 . Strings are, well, strings.
 . Date values are printed in the full date format in the local time zone,
   and accepted in the full format or any of the partial formats explained
   below.
 . Link values are printed as node designators. When given as an argument,
   node designators and key strings are both accepted.
 . Multilink values are printed as lists of node designators joined
   by commas.  When given as an argument, node designators and key
   strings are both accepted; an empty string, a single node, or a list
   of nodes joined by commas is accepted.

When property values must contain spaces, just surround the value with
quotes, either ' or ". A single space may also be backslash-quoted. If a
value must contain a quote character, it must be backslash-quoted or inside
quotes. Examples:
           hello world      (2 tokens: hello, world)
           "hello world"    (1 token: hello world)
           "Roch'e" Compaan (2 tokens: Roch'e Compaan)
           Roch\\'e Compaan  (2 tokens: Roch'e Compaan)
           address="1 2 3"  (1 token: address=1 2 3)
           \\\\               (1 token: \\)
           \\n\\r\\t           (1 token: a newline, carriage-return and tab)
           f "test\\"q"      (2 tokens: f test"q)

When multiple nodes are specified to the roundup get or roundup set
commands, the specified properties are retrieved or set on all the listed
nodes.

When multiple results are returned by the roundup get or roundup find
commands, they are printed one per line (default) or joined by commas (with
the -c) option.

Where the command changes data, a login name/password is required. The
login may be specified as either "name" or "name:password".
 . ROUNDUP_LOGIN environment variable
 . the -u command-line option
If either the name or password is not supplied, they are obtained from the
command-line. (See admin guide before using -u.)

Date format examples:
  "2000-04-17.03:45" means <Date 2000-04-17.08:45:00>
  "2000-04-17" means <Date 2000-04-17.00:00:00>
  "01-25" means <Date yyyy-01-25.00:00:00>
  "08-13.22:13" means <Date yyyy-08-14.03:13:00>
  "11-07.09:32:43" means <Date yyyy-11-07.14:32:43>
  "14:25" means <Date yyyy-mm-dd.19:25:00>

        Lists all instances of the given class. If the properties are not
        specified, all properties are displayed. By default, the column
        widths are the width of the largest value. The width may be
        explicitly defined by defining the property as "name:width".
        For example::

          roundup> table priority id,name:10
          Id Name
          1  fatal-bug
          2  bug
          3  usability
          4  feature

        Also to make the width of the column the width of the label,
        leave a trailing : without a width on the property. For example::

          roundup> table priority id,name:
          Id Name
          1  fata
          2  bug
          3  usab
          4  feat

        will result in a the 4 character wide "Name" column.
