#
# Makefile for sash
#
# The HAVE_GZIP definition adds the -gzip and -gunzip commands.
# The HAVE_LINUX_ATTR definition adds the -chattr and -lsattr commands.
# The HAVE_LINUX_CHROOT definition adds the -chroot command.
# The HAVE_LINUX_PIVOT definition adds the -pivot_root command.
# The HAVE_LINUX_LOSETUP definition adds the -losetup command.
# The HAVE_LINUX_MOUNT definition makes -mount and -umount work on Linux.
# The HAVE_BSD_MOUNT definition makes -mount and -umount work on BSD.
# The MOUNT_TYPE definition sets the default file system type for -mount.
#
# Note that the linker may show warnings about 'statically linked
# programs' requiring getpwnam, getpwuid, getgrnam and getgrgid.
# This is unavoidable since those routines use dynamic libraries anyway.
# Sash will still run, but if there are shared library problems then
# the user might have to be be careful when using the -chown, -chgrp,
# and -ls commands.
