= NAME

eruby - Embedded Ruby Language

= SYNOPSIS

eruby [options] [inputfile]

= DESCRIPTION

eruby interprets a Ruby code embedded text file. For example, eruby
enables you to embed a Ruby code to a HTML file.

A Ruby block starts with `<%' and ends with `%>'. eRuby replaces
the block with its output.

of the block.

If `<%' is followed by `#', the block is ignored as a comment.
