# This explorer returns script code string for running a command with su
# or sudo, whichever it founds. If searches the command in the order of
# first sudo and then su if sudo is not found.
# If no sudo nor su is found then it returns string script code to run
# first su and then sudo if su is not found.
# If no su nor sudo is found then it returns string script code to run
# bare command.
# It uses two arguments, first user and the second command to run.
# If the result string is assigned to foo it is used as:
# $ $foo user command
#
# first check sudo
