\begin{defundesc}{cgi-form-query}{}{data-alist}
 CGI scripts receive their parameters in various ways, depending on
 how they were called (e.g. by ``GET'' method). This procedure
 translates the delivered form data into an alist of decoded strings,
 using the environment variables set by the server
 (\ex{REQUEST\_METHOD}, \ex{QUERY\_STRING} (``GET'' script),
 \ex{CONTENT\_LENGTH} (``POST'' script)). So a query string like
 \codex{button=on\&\ob{}reply=Oh,\ob{}\%20yes} becomes alist
 \codex{(("button" . "on") ("reply" . "Oh, yes"))} This only works for
 GET and POST methods.
