Subject: How to reset a variable to the value in another variable?

All-

In line 8 in the code below, I want to reset the string variable "content2" with the value in string variable "intro". However, what I'm finding is that line 8 sets up "content2" as some type of pointer to "intro": The content2.gsub commands I'm making in lines 9 through 12 are affecting the value
of "intro" as if I were doing "intro.gsub" commands.

The solution has got to be simple, but it it illudes me. Your help appreciated! Thanks! -k euler

01   intro = ''
02   File.open("./input/intro_subtemplate.txt") { |f| intro = f.read }
03
04   content = File.new("./input/main_readme_template.txt").read
05
06   IO.foreach("./input/packages.txt") { |x|
07     field = x.chop.split('\t')
08     content2 = intro
09     content2.gsub!(/<intro_subtemplate.txt>/, intro)
10     content2.gsub!(/<prod_all_cap>/, field[2])
11     content2.gsub!(/<prod_title_cap>/, field[1])
12     content2.gsub!(/<op_sys>/, field[3])
13     File.open("./output/#{field[0]}", "w+") { |file| file.write(content2) }
14   }
