Comment(by reganeet):

 > So we need to both strip these out and figure out a method for you to
 edit files without introducing them.

 That's weird, since I think I've removed all the CRs, and in my emacs/vim
 there is no CR remaining in server_descriptors.py.

 > I'm not quite sure how we should handle this, logging a warning once if
 they try to verify without the module or something else...

 What about in RelayDescriptor.__init__:

 {{{
 if validate:
   try:
     if not self.is_valid():
       raise ValueError(self.nickname + " is not a valid server
 descriptor!")
   except ImportError:
     print("Unable to validate. Please install python-rsa module first.")
 }}}
