I. SUMMARY:
-----------------------------------------------------------------
The BlindElephant Web Application Fingerprinter attempts to discover the version
of a (known) web application by comparing static files at known locations against
precomputed hashes for versions of those files in all all available releases. 

The technique is fast, low-bandwidth, non-invasive, generic, and highly automatable.

II. PREREQUISITES:
-----------------------------------------------------------------
Python == 2.6.x (greater than 2.6.x may work, less than probably will not; neither is tested)


III. INSTALLATION (via distutils):
-----------------------------------------------------------------
python setup.py install


IV. EXAMPLE USAGE (command line):
-----------------------------------------------------------------
$ python BlindElephant.py 
Error: url and appName are required arguments unless using -l, -u, or -h

Usage: BlindElephant.py [options] url appName

Options:
  -h, --help            show this help message and exit
  -p PLUGINNAME, --pluginName=PLUGINNAME
                        Fingerprint version of plugin (should apply to web app
                        given in appname)
  -s, --skip            Skip fingerprinting webpp, just fingerprint plugin
  -n NUMPROBES, --numProbes=NUMPROBES
                        Number of files to fetch (more may increase accuracy).
                        Default: 15
  -w, --winnow          If more than one version are returned, use winnowing
                        to attempt to narrow it down (up to numProbes
                        additional requests).
  -l, --list            List supported webapps and plugins

Use "guess" as app or plugin name to attempt to attempt to
discover which supported apps/plugins are installed.

>>> 
>>> #Construct the fingerprinter
>>> #use default logger pointing to console; can pass "logger" arg to change output
>>> fp = WebAppFingerprinter("http://laws.qualys.com", "movabletype")

Possible versions: [LooseVersion ('4.22-en'), LooseVersion ('4.22-en-COM'), LooseVersion ('4.23-en'), LooseVersion ('4.23-en-COM')]
