NAME

       dacs_prenv - CGI program that displays its environment

SYNOPSIS

       dacs_prenv [-html]

DESCRIPTION

       This program is part of the DACS suite. It is a stand-alone program that neither accepts
       the usual DACS command line options (dacsoptions) nor accesses any DACS configuration
       files.

       This CGI utility simply prints its command line arguments, all environment variables,
       information about the system on which it is running, and CGI parameters and their values.
       It can be a useful tool when debugging web services.

           Tip
           This program can be a useful tool for debugging web services. Replace a call to your
           web service with an identical call to dacs_prenv to see what arguments your web
           service is being passed and (to some extent) other context.

OPTIONS

       dacs_prenv recognizes these command line flags:

       -html
           Selects HTML output (text/html) instead of the default Content-Type of text/plain, by
           default, using the style sheet dacs_prenv.css[1].

   Web Service Arguments
       When used as a web service, the following parameters are recognized:

       FORMAT
           At present, the only recognized value for this argument is HTML.

       just_dump_stdin
           If the value of QUERY_STRING is exactly jump_dump_stdin, then the program will simply
           copy its standard input to the standard output as text/plain.

FILES

       dacs_prenv.css[1]

DIAGNOSTICS

       The program exits 0 if everything was fine, 1 if an error occurred.

BUGS

       It should be possible to request XML output.
