Subject: Add script to format code, leaving the file untouched if not changed
X-Git-Tag: auth-4.3.0-alpha1~26^2~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ba5ba96c5009ccf969459d7bfaec83fb6191245d;p=thirdparty%2Fpdns.git

Add script to format code, leaving the file untouched if not changed
and report if it was changed.

Callable as separate script or with `make format-code` in toplevel
to reformat .cc and .hh files in the modules and pdns dirs.
