  91 RUN-PROGRAM is an external symbol in the EXTENSIONS package.
  92 Function: #<Function RUN-PROGRAM {12E7B79}>
  93 Function arguments:
  94   (program args &key (env *environment-list*) (wait t) pty input
  95    if-input-does-not-exist output (if-output-exists :error) (error :output)
  96    (if-error-exists :error) status-hook)
  97 Function documentation:
  98   Run-program creates a new process and runs the unix progam in the
  99    file specified by the simple-string program.  Args are the standard
 100    arguments that can be passed to a Unix program, for no arguments
 101    use NIL (which means just the name of the program is passed as arg 0).
 102
 103    Run program will either return NIL or a PROCESS structure.  See the CMU
 104    Common Lisp Users Manual for details about the PROCESS structure.
 105
 106    The keyword arguments have the following meanings:
 107      :env -
 108         An A-LIST mapping keyword environment variables to simple-string
 109         values.
 110      :wait -
 111         If non-NIL (default), wait until the created process finishes.  If
 112         NIL, continue running Lisp until the program finishes.
 113      :pty -
 114         Either T, NIL, or a stream.  Unless NIL, the subprocess is established
 115         under a PTY.  If :pty is a stream, all output to this pty is sent to
 116         this stream, otherwise the PROCESS-PTY slot is filled in with a stream
 117         connected to pty that can read output and write input.
 118      :input -
 119         Either T, NIL, a pathname, a stream, or :STREAM.  If T, the standard
 120         input for the current process is inherited.  If NIL, /dev/null
 121         is used.  If a pathname, the file so specified is used.  If a stream,
 122         all the input is read from that stream and send to the subprocess.  If
 123         :STREAM, the PROCESS-INPUT slot is filled in with a stream that sends
 124         its output to the process. Defaults to NIL.
 125      :if-input-does-not-exist (when :input is the name of a file) -
 126         can be one of:
 127            :error - generate an error.
 128            :create - create an empty file.
 129            nil (default) - return nil from run-program.
 130      :output -
 131         Either T, NIL, a pathname, a stream, or :STREAM.  If T, the standard
 132         output for the current process is inherited.  If NIL, /dev/null
 133         is used.  If a pathname, the file so specified is used.  If a stream,
 134         all the output from the process is written to this stream. If
 135         :STREAM, the PROCESS-OUTPUT slot is filled in with a stream that can
 136         be read to get the output. Defaults to NIL.
 137      :if-output-exists (when :input is the name of a file) -
 138         can be one of:
 139            :error (default) - generates an error if the file already exists.
 140            :supersede - output from the program supersedes the file.
 141            :append - output from the program is appended to the file.
 142            nil - run-program returns nil without doing anything.
 143      :error and :if-error-exists -
 144         Same as :output and :if-output-exists, except that :error can also be
 145         specified as :output in which case all error output is routed to the
 146         same place as normal output.
 147      :status-hook -
 148         This is a function the system calls whenever the status of the
 149         process changes.  The function takes the process as an argument.
 150 Its defined argument types are:
 151   (T T &KEY (:ENV T) (:WAIT T) (:PTY T) (:INPUT T) (:IF-INPUT-DOES-NOT-EXIST T)
 152    (:OUTPUT T) (:IF-OUTPUT-EXISTS T) (:ERROR T) (:IF-ERROR-EXISTS T)
 153    (:STATUS-HOOK T))
 154 Its result type is:
 155   (OR EXTENSIONS::PROCESS NULL)
