Default Sudo lecture

Here is a standard Sudo lecture, which can be seen at the user's first sudo run time (the following is an unmodified quote extracted from the sudo-$VERSION/plugins/sudoers/check.c source file found in the original sudo 1.8.6p7 source tarball):

#define DEFAULT_LECTURE "\n" \
    "We trust you have received the usual lecture from the local System\n" \
    "Administrator. It usually boils down to these three things:\n\n" \
    "    #1) Respect the privacy of others.\n" \
    "    #2) Think before you type.\n" \
    "    #3) With great power comes great responsibility.\n\n"
