We are going to want to not run sudo sometimes. So replace literal invocations of sudo with a variable, which is set to `sudo' by default, but can be overridden from the environment. No functional change if the environment variable is not set. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
wiringPi README =============== Please note that the official way to get wiringPi is via git from git.drogon.net and not GitHub. ie. git clone git://git.drogon.net/wiringPi The version of wiringPi held on GitHub by "Gadgetoid" is used to build the wiringPython, Ruby, Perl, etc. wrappers for these other languages. This version may lag the official Drogon release. Pull requests may not be accepted to Github.... Please see http://wiringpi.com/ for the official documentation, etc. and the best way to submit bug reports, etc. is by sending an email to projects@drogon.net Thanks! -Gordon
