According to Joseph Cheek:

No, that's not quite right. When a CGI script is called with the GET
method, the http server will partially parse the query string and pass it
as one or more command line arguments to the script. This is to allow
simple scripts to be written that just process their arguments, instead
of doing the decoding of the query string. I think this was a logical
extension of the old <ISINDEX> support.
However, htsearch does not get its input variables from the command line
arguments. If the environment variable REQUEST_METHOD is set to GET, it
will get the query string from the environment variable QUERY_STRING.
If REQUEST_METHOD is not set, it goes into query mode, and prompts the
user for certain values. Otherwise, it assumes the POST method, gets the
input size from the CONTENT_LENGTH env. variable, and reads that many
bytes from the standard input (the socket from the HTTP connection).
The only reason I suggested passing on command line arguments in the
wrapper script is if you want to run htsearch in interactive mode, and
run the wrapper rather than the real htsearch program. In this case,
you may want to specify -v or -c conf options, which the wrapper should
pass on to the real program. These are the only arguments htsearch uses,
hence the spartan usage message.
