 Practice is to run rpmbuild as non-root user. This prevents inadvertently
 installing files in the operating system. The intent is to run build_rpms.bsh
 as a non-root user with sudo privileges. If you have a different command for
-sudo, or do not have sudo installed (which is possible, but unlikely), you can
-set the SUDO environment variable to nothing or another command and you can
-run as root if that is your style. Example:
-
-```
-./clean.bsh
-SUDO=echo ./build_rpms.bsh
-  or
-(as root) SUDO= ./build_rpms.bsh
-```
-
-(The echo example will let you know what yum commands you need to run to make
-the build work in case you care. Most of people will just run
-```./build_rpms.bsh``` and be done.)
+sudo, set the SUDO environment variable to the other command.
 
 When all is down, install (or distribute) RPMS/git-lfs.rpm
