# SOAP/WSDL 
#
#
# == Examples
# 
# class API < Bio::SOAPWSDL
#   def initialize
#     @wsdl = 'http://example.com/example.wsdl'
#     @log = File.new("soap_log", 'w')
#     create_driver
#   end
# end
#
# == Use HTTP proxy
#
# You need to set following two environmental variables
# (case might be insensitive) as required by SOAP4R.
#
# --- soap_use_proxy
# Set the value of this variable to 'on'.
#
# --- http_proxy
# Set the URL of your proxy server (http://myproxy.com:8080 etc.).
#
# === Example
# 
# % export soap_use_proxy=on
# % export http_proxy=http://localhost:8080
