NAME

       inc - incorporate new mail

SYNOPSIS

       inc [+folder] [-audit audit-file] [-noaudit] [-changecur | -nochangecur] [-form formfile]
            [-file name] [-silent | -nosilent] [-truncate | -notruncate] [-width columns]
            [-Version] [-help]

DESCRIPTION

       Inc incorporates mail from the user's incoming mail drop into an mh folder.

       You  may  specify  which  folder to use with +folder.  If no folder is specified, then inc
       will use either the folder given by a (non-empty) `Inbox' entry in the user's profile,  or
       the  folder  named  `inbox'.  If the specified (or default) folder doesn't exist, the user
       will (in -nosilent mode) be queried prior to its creation.

       When the new messages are incorporated into the folder, they are assigned numbers starting
       with  the  next  highest  number  for  the  folder.  As the messages are processed, a scan
       listing of the new mail is produced.

       If the user's profile contains a  `Msg-Protect:  nnn'  entry,  it  will  be  used  as  the
       protection  on the newly created messages, otherwise the mmh default of 0644 will be used.
       For all subsequent operations on these messages, this initially assigned  protection  will
       be preserved.

       If the switch -audit audit-file is specified (usually as a default switch in the profile),
       then inc will append a header line and a line per message to  the  end  of  the  specified
       audit-file with the format:

            <<inc>> date
            <scan line for first message>
            <scan line for second message>
            <etc.>

       This is useful for keeping track of volume and source of incoming mail.  Eventually, repl,
       forw, comp, and dist may also produce audits to  this  (or  another)  file,  perhaps  with
       `Message-Id' information to keep an exact correspondence history.  `Audit-file' will be in
       the current directory unless a full path is specified.

       Inc will incorporate even  improperly  formatted  messages  into  the  user's  mh  folder,
       inserting a blank line prior to the offending component and printing a comment identifying
       the bad message.

       In all cases, the user's mail drop will be zeroed, unless the -notruncate switch is given.

       If the profile entry `Unseen-Sequence' is present and non-empty, then inc will add each of
       the newly incorporated messages to each sequence named by the profile entry.  Inc will not
       zero each sequence prior to adding messages.

       The interpretation of the -form formatfile, and -width columns switches is the same as  in
       scan.

       By  using  the  -file  name switch, one can direct inc to incorporate messages from a file
       other than the user's maildrop.  In particular, if name is `-' then inc will read messages
       from  standard  input.   Note that the named file will NOT be zeroed, unless the -truncate
       switch is given.

       If the environment variable $MAILDROP is set, then inc uses it  as  the  location  of  the
       user's  maildrop  instead  of  the  default  (the  -file name switch still overrides this,
       however).  If this environment variable is not set, then  inc  will  consult  the  profile
       entry  `MailDrop'  for  this  information.  If the value found is not absolute, then it is
       interpreted relative to the user's mh directory.  If the value is not found, then inc will
       look in the standard system location for the user's maildrop.

       The  -silent  switch  directs  inc  to be quiet and not ask any questions at all.  This is
       useful for putting inc in the background and going on to other things.

FILES

       $HOME/.mmh/profile         The user profile
       /var/mail/$USER            Location of mail drop

PROFILE COMPONENTS

       Path:                To determine the user's mail storage
       Alternate-Mailboxes: To determine the user's mailboxes
       Inbox:               To determine the inbox, default `inbox'
       Folder-Protect:      To set mode when creating a new folder
       Msg-Protect:         To set mode when creating a new message and audit-file
       Unseen-Sequence:     To name sequences denoting unseen messages

SEE ALSO

       scan(1), mh-mail(5)

DEFAULTS

       `+folder' defaulted by `Inbox' above
       `-noaudit'
       `-changecur'
       `-form' defaulted as described above
       `-nosilent'
       `-truncate' if `-file name' not given, `-notruncate' otherwise
       `-width' defaulted to the width of the terminal

CONTEXT

       The folder into which messages are being incorporated will become the current folder.  The
       first message incorporated will become the current message, unless the -nochangecur option
       is specified.  This leaves the context ready for a show of the first new message.
