# A subclass of ERB that writes directly to an IO. Credit to Aaron Patterson
# and Masatoshi SEKI.
#
# To use:
#
# erbio = RDoc::ERBIO.new '<%= "hello world" %>', nil, nil
#
# open 'hello.txt', 'w' do |io|
# erbio.result binding
# end
#
# Note that binding must enclose the io you wish to output on.
class RDoc::ERBIO < ERB
##
# Defaults +eoutvar+ to 'io', otherwise is identical to ERB's initialize
def initialize str, safe_level = nil, trim_mode = nil, eoutvar = 'io'

# Instructs +compiler+ how to write to +io_variable+
