There are some tricks we have not mentioned yet about the pkg-* files that come in handy sometimes.

9.1. pkg-message

To display a message when the package is installed, place the message in pkg-message. This capability is often useful to display additional installation steps to be taken after a pkg install or to display licensing information.

When some lines about the build-time knobs or warnings have to be displayed, use ECHO_MSG. pkg-message is only for post-installation steps. Likewise, the distinction between ECHO_MSG is for printing informational text to the screen and ECHO_CMD is for command pipelining:

	@${ECHO_MSG} "updating /etc/shells"
	@${CP} /etc/shells /etc/shells.bak
	@( ${GREP} -v ${PREFIX}/bin/bash /etc/shells.bak; \
		${ECHO_CMD} ${PREFIX}/bin/bash) >/etc/shells
	@${RM} /etc/shells.bak


Do not add an entry for pkg-message in pkg-plist.
