-"""CGI-savvy HTTP Server.
-
-This module builds on SimpleHTTPServer by implementing GET and POST
-requests to cgi-bin scripts.
-
-If the os.fork() function is not present (e.g. on Windows),
-os.popen2() is used as a fallback, with slightly altered semantics; if
-that function is not present either (e.g. on Macintosh), only Python
-scripts are supported, and they are executed by the current process.
-
-In all cases, the implementation is intentionally naive -- all
-requests are executed sychronously.
-
-SECURITY WARNING: DON'T USE THIS CODE UNLESS YOU ARE INSIDE A FIREWALL
--- it may execute arbitrary Python code or external programs.
-
-Note that status code 200 is sent prior to execution of a CGI script, so
-scripts cannot send other status codes such as 302 (redirect).
