Miscellaneous sys File Commands
-------------------------------

`sequence BOOLEAN'
     If BOOLEAN is true, then conversation sequencing is automatically
     used for the remote system, so that if somebody manages to spoof
     as the remote system, it will be detected the next time the remote
     system actually calls.  This is false by default.

`command-path STRINGS'
     Specifies the path (a list of whitespace separated directories) to
     be searched to locate commands to execute.  This is only used for
     commands requested by `uux', not for chat programs.  The default
     is from `policy.h'.

`commands STRINGS'
     The list of commands which the remote system is permitted to
     execute locally.  For example: `commands rnews rmail'.  If the
     value is `ALL' (case significant), all commands may be executed.
     The default is `rnews rmail'.

`free-space NUMBER'
     Specify the minimum amount of file system space (in bytes) to
     leave free after receiving a file.  If the incoming file will not
     fit, it will be rejected.  This initial rejection will only work
     when talking to another instance of this package, since older UUCP
     packages do not provide the file size of incoming files.  Also,
     while a file is being received, `uucico' will periodically check
     the amount of free space.  If it drops below the amount given by
     the `free-space' command, the file transfer will be aborted.  The
     default amount of space to leave free is from `policy.h'.  This
     file space checking may not work on all systems.

`pubdir STRING'
     Specifies the public directory that is used when `~' is specifed in
     a file transfer or a list of directories.  This essentially
     overrides the public directory specified in the main configuration
     file for this system only.  The default is the public directory
     specified in the main configuration file (which defaults to a
     value from `policy.h').

`debug STRING ...'
     Set additional debugging for calls to or from the system.  This
     may be used to debug a connection with a specific system.  It is
     particularly useful when debugging incoming calls, since debugging
     information will be generated whenever the call comes in.  See the
     `debug' command in the main configuration file (*note Debugging
     Levels::.) for more details.  The debugging information specified
     here is in addition to that specified in the main configuration
     file or on the command line.

`max-remote-debug STRING ...'
     When the system calls in, it may request that the debugging level
     be set to a certain value.  The `max-remote-debug' command may be
     used to put a limit on the debugging level which the system may
     request, to avoid filling up the disk with debugging information.
     Only the debugging types named in the `max-remote-debug' command
     may be turned on by the remote system.  To prohibit any debugging,
     use `max-remote-debug none'.
