I want to do a simple regex replace on a file. I want to replace this
multiline match

<!--scripts-->[\\S\\s]*?<!--endscripts-->

with this string:

<script type="text/javascript" src="/path/to/javascript.js"></script>

How can I do this with ruby assuming my file is: /html/page.html

As far as I see for multilines the -i option doesn't work.
You could do something like

whole = File.read "fname"
whole.gsub! /.../m, "..."
File.open "fname.mod" do |f| f.write whole end

Sorry, but I suppose the best tool for this task is Vim.
