Usage

Overview

erb interprets a Ruby code embedded text file. For example, erb enables you to embed a Ruby code to a HTML file. A Ruby block starts with `<%' and ends with `%>'. erb replaces the block with its output. If `<%' is followed by `=', eRuby replaces the block with a value of the block. If `<%' is followed by `#', the block is ignored as a comment.
