+# Adjust post-install permissions settings.  This rule works off two
+# specially-formatted variables, INSTALLPERMS_exec and INSTALLPERMS_data. 
+# Each is a whitespace-separated list of commands, all of which are either
+# a variable assignment or a filename.  Three variables are available:
+#
+#  - dest= sets the destination directory to e.g., $(sbindir)
+#  - chown= controls changes in ownership; value is first argument to chown
+#  - chmod= controls changes in permissions; value is first argument to chmod
+#
+# As a special case, chown=amanda is taken as equivalent to 
+# chown=$(BINARY_OWNER):$(SETUID_GROUP), which may otherwise have problems with
+# whitespace in the user/group names.
+# 
+# when a filename is seen, the currently active variables are applied.
+#
+# Note that scripts are data, not executables!
+#
+# EXAMPLE
+#
+# sbin_PROGRAMS = foo bar bing
+# libexec_PROGRAMS = pro gram
+# sbin_SCRIPTS = sk ript
+# INSTALLPERMS_exec = \
+#      dest=$(sbindir) chown=amanda chmod= \
+#              foo bar \
+#      chmod=u+s,o-rwx \
+#              bing
+#      dest=$(libexecdir) chmod= \
+#              $(libexec_PROGRAMS)
+# INSTALLPERMS_data = \
+#      dest=$(sbindir) chown=amanda chmod= \
+#              $(sbin_SCRIPTS)
+#
+# This whole operation is not required when making builds for packaging,
+# and can be disabled with --disable-installperms, via the WANT_INSTALLPERMS
+# AM_CONDITIONAL.
