/*
Well... for each line of the file you are trying to match 2 lines. 
That's impossible :). Read the file in "paragraph mode" and match each 
paragraph, or read it whole and scan it for your regexp.

Strike, ouch ;-) 
yup line != lines

/*
For example (not tested):

File.read('...').scan(/^(\w+)\s*\n\w+=(\w+)$/) {|a,b| puts a+": "+b}
*/

works like a charm. Thanks !!
