Subject: Parsing text files with dynamic contents

------=_Part_19493_2421895.1170365710787
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Content-Transfer-Encoding: 7bit
Content-Disposition: inline

Let's guess a simple example: i need to parse a text file, wityh variables
inside, and then output again the resulting text to a file or to screen.

-------------start example text------------

hello, it is #{now}, your name is #{name}


-------------end example text------------

variables could be written also $var, or whatever else could be better.

but obviously when i do

file.each do |line|
   puts line     #here i need to do something to find the variable and
output the correct value
end

How would you ruby experts do the correct parsing to output values instead
of the text content? Is there any class available that do this?

Thank you very much for helping
