This module provides basic functions to evaluate plural ERB files(.rhtml)
in a <a href="TextDomain.html">TextDomain</a>. You need to implement a
class which includes <a href="ErbContainer.html">GetText::ErbContainer</a>.
</p>
<p>
See simple examples below:
</p>
<pre>
require 'gettext/erb'
class SimpleContainer
include GetText::ErbContainer
def initialize(domainname, domainpath = nil, locale = nil, charset = nil)
bindtextdomain(domainname, domainpath, locale)
end
end
container = SimpleContainer.new("helloerb1", "locale")
puts container.eval_file("/your/erb/file.rhtml")
</pre>
<p>
This module is an example for template engines such as ERB. You can
implement another implementation easily to read gettext/erb.rb.
