 # This garbage is necessary because on windows, Travis

 # The block here repeats the clone after having unset
 # core.autcrlf. There is no simple way to do this
 # conditionally on OS because windows will not allow
 # a file to be removed or moved while the file is open,
 # and we use constructed paths to scripts to get
 # conditional execution.
 #
 # Happy windowsing!
