    All non-error messages and output will be written to this file (default is stderr).

-errmsgpre     tag

    Allows developer to set the first portion of all ploticus error messages to tag for purposes of presentation or identification.

-errfile     filename | stderr | stdout

    All error messages will be written to this file (default is stderr).


    The -noshell command line option is intended to disallow any shell commands that a user might supply in a script from being executed. The following script constructs are disabled when -noshell is in effect:
     #proc getdata
       command:   myshellcommand
     #proc getdata
       file:    filename  (because this allows shell expansion of wild cards)
       (use "pathname" instead)
