       withlist  -  General  framework  for  interacting  with  a mailing list


       withlist [options] listname [args ...]

       There  are  two   ways   to   use   this   script:   interactively   or
       programmatically.   Using  it  interactively  allows  you to play with,
       examine  and  modify  a  MailList  object  from  Python's   interactive
       interpreter.   When running interactively, a MailList object called `m'
       will be available in the global namespace.  It  also  loads  the  class
       MailList into the global namespace.

       Programmatically,  you  can  write  a function to operate on a MailList
       object, and this script will take care of the housekeeping  (see  below
       for examples).  In that case, the general usage syntax is:


       -l, --lock
              Lock  the  list  when  opening.   Normally  the  list  is opened
              unlocked (e.g. for read-only operations).  You can  always  lock
              the file after the fact by typing `m.Lock()'

              Note  that  if  you  use this option, you should explicitly call
              m.Save()  before  exiting,  since  the  interpreter's  clean  up
              procedure  will  not  automatically save changes to the MailList
              object (but it will unlock the list).

       -i, --interactive
              Leaves you at an interactive prompt after all  other  processing
              is complete.  This is the default unless the -r option is given.

       -r [module.]callable, --run [module.]callable
              This can be used to  run  a  script  with  the  opened  MailList
              object.   This  works by attempting to import module (which must
              already be  accessible  on  your  sys.path),  and  then  calling
              callable  from the module.  callable can be a class or function;
              it is called with the MailList object as the first argument.  If
              additional  args  are given on the command line, they are passed
              as subsequent positional args to the callable.

              Note that module. is optional; if it is omitted  then  a  module
              with the name callable will be imported.

              The global variable `r' will be set to the results of this call.

       -a, --all
              This option only works with the -r option.  Use this if you want
              to execute the script on all mailing lists.  When you use -a you
              should not include a listname argument on the command line.  The
              variable `r' will be a list of all the results.

       -q, --quiet
              Suppress all status messages.

       -h, --help
              Print a small help text and exit.


       Here's  an example of how to use the -r option.  Say you have a file in
       the Mailman  installation  directory  called  `',  with  the
       following two functions:

         def listaddr(mlist):
             print mlist.GetListEmail()

         def requestaddr(mlist):
             print mlist.GetRequestEmail()

       Now,  from the command line you can print the list's posting address by
       running the following from the command line:

         % bin/withlist -r listaddr mylist
         Loading list: mylist (unlocked)
         Importing listaddr ...
         Running listaddr.listaddr() ...

       And you can print the list's request address by running:

         % bin/withlist -r listaddr.requestaddr mylist
         Loading list: mylist (unlocked)
         Importing listaddr ...
         Running listaddr.requestaddr() ...

       As another example, say  you  wanted  to  change  the  password  for  a
       particular  user  on  a  particular  list.  You could put the following
       function in a file called `':

         from Mailman.Errors import NotAMemberError

         def changepw(mlist, addr, newpasswd):
                 mlist.setMemberPassword(addr, newpasswd)
             except NotAMemberError:
                 print 'No address matched:', addr

        and run this from the command line:
        % bin/withlist -l -r changepw mylist foobar
