This is a Haskell library for writing CGI programs. Its features include:

• Access to CGI parameters (e.g. form input) from both GET and POST requests.
• Access to CGI environment variables.
• Ability to set arbitrary response headers.
• Support for HTTP cookies.
• An efficient implementation of multipart/form-data using Data.ByteString. This allows for efficient handling of file uploads.
• A CGI monad transformer.
• Basic exception handling and logging (these should be improved)
• Low-level run functions that allow using programs written with this package with protocols other than CGI, for example FastCGI.
