Permissions problem. Make sure that all cgi-bin scripts are world readable
and world executable. Also, all directories in their path are world readable
and executable. These scripts are accessed with a userid of "nobody" (uid
usually ~65000) so the .py files have to be executable by the "others"
permission group and the directory in which they are contained has to have
permissions for "others" to access them.

Basically you have to allow everybody to access them so that "nobody" can
execute them. Rather a bad pun, I must say... :-)

HTTP_ALL_HEADERS is being set so that we can echo the headers back to the
user in their raw form. The new http_server simply concatenates the headers
received in the raw form into an env. variable before handing over
processing to the python library's CGIHTTPServer. This env. variable is
accessed in the echo_headers.py and echoed back to the client.
