+# Before including this file, the module Makefile must define these

#
-# The first rule in this file is a rule for "all", which causes both the

-# install: install-headers install-lib $(install-shlib-dep)
+# This makefile provides the following (phony) targets:
#
-# where install-headers is only needed if you have header files to install
-# (and, of course, it has to be provided by your makefile). The rules
-# install-lib and install-shlib are provided by this makefile --- they
-# automatically install the plain and shared libraries into $(LIBDIR).
-# install-shlib-dep is a variable that expands to install-shlib if the
-# shared library needs to be installed, empty if not.
+# all-lib build the static and shared (if applicable) libraries
+# install-lib install the libraries into $(libdir)
+# uninstall-lib remove the libraries from $(libdir)

#
-# Got that? Look at src/interfaces/libpq/Makefile.in for an example.
+# Since `all-lib' is the first rule in this file you probably want to
+# have the `all' target before including this file. In the most simple
+# case it would look like this:
+#
+# all: all-lib
+#
+# Similarly, the install rule might look like
+#
+# install: install-lib
+#
+# plus any additional things you want to install. Et cetera.
