description = [[

Tries to find out the technology behind the target website.

The script checks for certain defaults that might not have been changed, like
common headers or URLs or HTML content.

While the script does some guessing, note that overall there's no way to
determine what technologies a given site is using.

You can help improve this script by adding new entries to
nselib/data/http-devframework-fingerprints.lua

Each entry must have:
* <code>rapidDetect</code> - Callback function that is called in the beginning
of detection process. It takes the host and port of target website as arguments.
* <code>consumingDetect</code> - Callback function that is called for each
spidered page. It takes the body of the response (HTML code) and the requested
path as arguments.

Note that the <code>consumingDetect</code> callback will not take place only if
<code>rapid</code> option is enabled.

-- @args http-devframework.rapid boolean value that determines if a rapid detection

--       is that second one requires crawling through the website. Default: false
--       (lengthy detection is performed)
-- @args http-devframework.fingerprintfile File containing fingerprints. Default: nselib/data/http-devframework-fingerprints.lua
