# SysV /etc/install, /usr/sbin/install

# SunOS /usr/etc/install

# IRIX /sbin/install

# AIX /bin/install

# AFS /usr/afsws/bin/install, which mishandles nonexistent args

# SVR4 /usr/ucb/install, which tries to use the nonexistent group "staff"

# ./install, which can be erroneously created by make from ./install.sh.
