+#   installed -- just the basic library names.  E.g. "libfoo libbar"
+#
+# SHLIB_SUFFIX: Shared library filename suffix, e.g. "so".
+#
+# MAJ: Library major version number, e.g. "3" in file name "libfoo.3.1"
+#
+# MIN: Library minor version number, e.g. "1" in file name "libfoo.3.1"
+#
+# LDFLAGS_SHLIB: linker (Ld) flags needed to link object files together into
+#   a shared library.  May use $(SONAME) for the soname of the library.
+#   Include -lc if appropriate.
+#
+# LADD: Additional linker flags (normally set on the make command line).
+#
+# INSTALL_DATA: beginning of shell command to install a library file.
+#
+# DESTDIR: main installation directory
+#
+# LIBINST_DIR: directory in which to install libraries, relative to DESTDIR.
