Use a class 'ERuby::Compiler'.
This class has following instance methods:
  - compile_file(File)
  - compile_string(String)

Example:
    --------------------
    require 'eruby'
    filename = 'hoge.rhtml'
    compiler = ERuby::Compiler.new()
    src = nil
    File.open(filename) do |file|
        src = compiler.compile_file(file)
    end
    print src
    --------------------

    --------------------
    require 'eruby'
    filename = 'hoge.rhtml'
    file_str = nil
    File.open(filename) do |file|
      file_str = file.read()
    end
    compiler = ERuby::Compiler.new()
    src = compiler.compile_string(file_str)
    print src
    --------------------
