+.TH SU 1 ubase-VERSION
+.SH NAME
+BsuR - Run a command with a substitute user and group ID
+.SH SYNOPSIS
+BsuR [B-lpR] [IuserR]
+.SH DESCRIPTION
+BsuR allows to run commands with a substitute user and group ID.
+When called without arguments, su defaults to running an interactive shell
+as root. For backward compatibility su defaults to not change the current
+directory and to only set the environment variables BHOMER and BSHELLR
+(plus BUSERR and BLOGNAMER if target IuserR is not root).
+.SH OPTIONS
+.TP
+B-lR
+Starts the shell as login shell with an environment similar to a real
+login.
+.TP
+B-pR
+Preserves the whole environment. This option is ignored if the B-lR
+option is specified.
