File Transfer Control
---------------------

`send-request BOOLEAN'
     The BOOLEAN determines whether the remote system is permitted to
     request files from the local system.  The default is yes.

`receive-request BOOLEAN'
     The BOOLEAN determines whether the remote system is permitted to
     send files to the local system.  The default is yes.

`request BOOLEAN'
     A shorthand command, equivalent to specifying both `send-request
     BOOLEAN' and `receive-request BOOLEAN'.

`call-transfer BOOLEAN'
     The BOOLEAN is checked when the local system places the call.  It
     determines whether the local system may do file transfers queued
     up for the remote system.  The default is yes.

`called-transfer BOOLEAN'
     The BOOLEAN is checked when the remote system calls in.  It
     determines whether the local system may do file transfers queued
     up for the remote system.  The default is yes.

`transfer BOOLEAN'
     A shorthand command, equivalent to specifying both `call-transfer
     BOOLEAN' and `called-transfer BOOLEAN'.

`call-local-size NUMBER STRING'
     The STRING is a time string (see Time Strings.).  The NUMBER
     is the size in bytes of the largest file that should be
     transferred at a time matching the time string, if the local system
     placed the call and the request was made by the local system.  This
     command may appear multiple times in a single alternate.  If this
     command does not appear, or if none of the time strings match,
     there are no size restrictions.

     With all the size control commands, the size of a file from the
     remote system (as opposed to a file from the local system) will
     only be checked if the other system is running this package: other
     UUCP packages will not understand a maximum size request, nor will
     they provide the size of remote files.

`call-remote-size NUMBER STRING'
     Specify the size in bytes of the largest file that should be
     transferred at a given time by remote request, when the local
     system placed the call.  This command may appear multiple times in
     a single alternate.  If this command does not appear, there are no
     size restrictions.

`called-local-size NUMBER STRING'
     Specify the size in bytes of the largest file that should be
     transferred at a given time by local request, when the remote
     system placed the call.  This command may appear multiple times in
     a single alternate. If this command does not appear, there are no
     size restrictions.

`called-remote-size NUMBER STRING'
     Specify the size in bytes of the largest file that should be
     transferred at a given time by remote request, when the remote
     system placed the call.  This command may appear multiple times in
     a single alternate. If this command does not appear, there are no
     size restrictions.

`local-send STRINGS'
     Specifies that files in the directories named by the STRINGS may
     be sent to the remote system when requested locally (using `uucp'
     or `uux').  The directories in the list should be separated by
     whitespace.  A `~' may be used for the public directory.  On a Unix
     system, this is typically `/usr/spool/uucppublic'; the public
     directory may be set with the `pubdir' command.  Here is an example
     of `local-send':

          local-send ~ /usr/spool/ftp/pub

     Listing a directory allows all files within the directory and all
     subdirectories to be sent.  Directories may be excluded by
     preceding them with an exclamation point.  For example:

          local-send /usr/ftp !/usr/ftp/private ~

     means that all files in `/usr/ftp' or the public directory may be
     sent, except those files in `/usr/ftp/private'.  The list of
     directories is read from left to right, and the last directory to
     apply takes effect; this means that directories should be listed
     from top down.  The default is the root directory (i.e., any file
     at all may be sent by local request).

`remote-send STRINGS'
     Specifies that files in the named directories may be sent to the
     remote system when requested by the remote system.  The default is
     `~'.

`local-receive STRINGS'
     Specifies that files may be received into the named directories
     when requested by a local user.  The default is `~'.

`remote-receive STRINGS'
     Specifies that files may be received into the named directories
     when requested by the remote system.  The default is `~'.  On
     Unix, the remote system may only request that files be received
     into directories that are writeable by the world, regardless of
     how this is set.

`forward-to STRINGS'
     Specifies a list of systems to which files may be forwarded.  The
     remote system may forward files through the local system on to any
     of the systems in this list.  The string `ANY' may be used to
     permit forwarding to any system.  The default is to not permit
     forwarding to other systems.  Note that if the remote system is
     permitted to execute the `uucp' command, it effectively has the
     ability to forward to any system.

`forward-from STRINGS'
     Specifies a list of systems from which files may be forwarded.  The
     remote system may request files via the local system from any of
     the systems in this list.  The string `ANY' may be used to permit
     forwarding to any system.  The default is to not permit forwarding
     from other systems.  Note that if a remote system is permitted to
     execute the `uucp' command, it effectively has the ability to
     request files from any system.

`forward STRINGS'
     Equivalent to specifying both `forward-to STRINGS' and
     `forward-from STRINGS'.  This would normally be used rather than
     either of the more specific commands.
