|

# for passing an HTTP request from a web server to a

# standalone program, and returning the output to the web
|
||||
# browser. Basically, a CGI program is called with the

# parameters of the request passed in either in the

# environment (GET) or via $stdin (POST), and everything
|
||||
# it prints to $stdout is returned to the client.

# This file holds the +CGI+ class. This class provides
|

# managing cookies, and generating HTML output. See the

# class documentation for more details and examples of use.
