description
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.
