Z:englobe-dpkg-man--a90d1d-When B=3Cdpkg-buildpackage=3E need/es

When B needs to execute part of the build process as root, it prefixes the command it executes with I if one has been specified. Otherwise, if none has been specified, B will be used by default, if the command is present. I should be the name of a program on the B and will get as arguments the name of the real command to run and the arguments it should take. I should not contain spaces or any other shell metacharacters. I might typically be B, B , B or B. B is not suitable, since it requires a B<-c> option to run a command and even then it can only invoke the user's shell with B<-c> instead of passing arguments individually to the command to be run.
