+#
+# Print a pkgsrc status message and show phase messages as the terminal
+# title.  With SMART_MESSAGES defined, phase messages carry the make target
+# and the stack of packages being built (see _PKGSRC_IN in bsd.pkg.mk):
+#
+#      ===> target [pkg dep ...] ===> message
+#
+# When the title can be set, the stack becomes the title and only
+# "===> message" is printed.  Otherwise the message is printed unchanged.
+#
+# To use it, add to /etc/mk.conf:
+#
+#      ECHO_MSG=       ${PKGSRCDIR}/mk/scripts/echo-msg
+#      SMART_MESSAGES= yes

+       Usage:  ${PROG} [message ...]
+
+       Print the message like echo(1).  When standard output is a
+       terminal, also show phase ("===>") messages as the tmux pane
+       or terminal title.  With SMART_MESSAGES, the title shows the
+       stack of packages being built, and the target and stack are
+       left out of the printed message.  Other messages leave the
+       title alone.
+
+       Options:
+       -h      Show this help
+       USAGE
