     folders is equivalent to folder -all


       Since the nmh environment is the shell, it is easy to lose track of the
       current folder from day to day.  When  folder  is  given  the  `-print'
       switch  (the  default), folder will list the current folder, the number
       of messages in it, the range of the messages (low-high), and  the  cur-
       rent  message  within  the  folder,  and  will flag extra files if they
       exist.  An example of this summary is:

       inbox+            has  16 messages (  3- 22); cur=  5.

       If a `+folder' and/or `msg' are specified, they will become the current
       folder  and/or  message.   By  comparison, when a `+folder' argument is
       given, this corresponds to a "cd"  operation  in  the  shell;  when  no
       `+folder' argument is given, this corresponds roughly to a "pwd" opera-
       tion in the shell.

       If the specified (or default) folder doesn't exist, the default  action
       is  to  query the user as to whether the folder should be created; when
       standard input is not a tty, the answer to the query is assumed  to  be

       Specifying  `-create'  will  cause folder to create new folders without
       any query.  (This is the easy way to create an  empty  folder  for  use
       later.)   Specifying `-nocreate' will cause folder to exit without cre-
       ating a non-existant folder.

   Multiple Folders
       Specifying `-all' will produce a summary line for each top-level folder
       in  the  user's  nmh  directory,  sorted alphabetically.  (If folder is
       invoked by a name ending with "s" (e.g., folders ), `-all' is assumed).
       Specifying `-recurse' with `-all' will also produce a line for all sub-
       folders.  These folders are all  preceded  by  the  read-only  folders,
       which occur as "atr-cur-" entries in the user's nmh context.  For exam-
       FOLDER                  # MESSAGES RANGE      CUR     (OTHERS)
       /var/work/folder  has  35 messages ( 1- 35);  cur=23.
       /usr/bugs/Mail    has  82 messages ( 1-108);  cur=82.
       ff                has  no messages.
       inbox+            has  16 messages ( 3- 22);  cur= 5.
       mh                has  76 messages (15- 76);  cur=70.
       notes             has   2 messages ( 1-  2);  cur= 1.
       ucom              has 124 messages ( 1-124);  cur= 6; (others).

       TOTAL = 339 messages in 7 folders

       The "+" after inbox indicates that  it  is  the  current  folder.   The
       "(others)" indicates that the folder `ucom' has files which aren't mes-
       sages.  These files may either be  sub-folders,  or  files  that  don't
       belong under the nmh file naming scheme.

       The header is output if either a `-all' or a `-header' switch is speci-
       fied.  It is suppressed by `-noheader'.

       The folder and message totals are  output  if  either  a  `-all'  or  a
       `-total' switch is specified.  It is suppressed by `-nototal'.

       If  `-fast'  is  given,  only  the folder name (or names in the case of
       `-all') will be listed.  (This is faster because the folders  need  not
       be read.)

       If  a  `+folder' is given along with the `-all' switch, folder will, in
       addition to setting the current folder, list the  top-level  subfolders
       for  the  current  folder  (with  `-norecurse') or list all sub-folders
       under the current folder recursively (with `-recurse').  In this  case,
       if  a  `msg'  is  also  supplied, it will become the current message of

       The `-recurse' switch lists each folder recursively,  so  use  of  this
       option effectively defeats the speed enhancement of the `-fast' option,
       since each folder must be searched for subfolders.   Nevertheless,  the
       combination of these options is useful.

   Compacting a Folder
       The  `-pack'  switch  will compress the message names in the designated
       folders, removing holes in message numbering.   The  `-verbose'  switch
       directs  folder  to tell the user the general actions that it is taking
       to compress the folder.

   The Folder Stack
       The `-push' switch directs folder to push the current folder  onto  the
       folder-stack,  and  make the `+folder' argument the current folder.  If
       `+folder' is  not  given,  the  current  folder  and  the  top  of  the
       folder-stack  are exchanged.  This corresponds to the "pushd" operation
       in the CShell.

       The  `-pop'  switch  directs  folder  to  discard  the   top   of   the
       folder-stack,  after  setting  the  current  folder  to that value.  No
       `+folder' argument is allowed.  This corresponds to the  "popd"  opera-
       tion in the CShell.  The `-push' switch and the `-pop' switch are mutu-
       ally exclusive: the last occurrence of either one overrides any  previ-
       ous  occurrence  of the other.  Both of these switches also set `-list'
       by default.

       The  `-list'  switch  directs  folder  to  list  the  contents  of  the
       folder-stack.   No  `+folder'  argument is allowed.  After a successful
       `-push' or `-pop', the `-list' action  is  taken,  unless  a  `-nolist'
       switch  follows  them  on  the  command  line.  This corresponds to the
       "dirs" operation in the  CShell.   The  `-push',  `-pop',  and  `-list'
       switches turn off `-print'.

       `+folder' defaults to the current folder

       `-print' is the default if no `-list', `-push', or `-pop' is specified
       `-list' is the default if `-push', or `-pop' is specified


       If  `+folder'  and/or  `msg'  are  given,  they will become the current
       folder and/or message.


       There is no way to restore  the  default  behavior  (to  ask  the  user
       whether to create a non-existant folder) after `-create' or `-nocreate'
       is given.
