Being lazy, forgetful and generally very bad with regular expressions 
leads me to post this question:

How can I use the contents of a variable as a pattern in a regular 
expression?

I get a list of files from a set of paths and I want to do the following

repo=list_files paths
repo.collect!{|entry|
	entry.gsub(/{variable_with_the root_I_want_to_substitute}/,"")
}

pretty straightforward no?
