 Libraries are ranlib'd when made.
+
+In addition, a reduced version of a library, including just specific
+objects that are compiled with additional options to reduce their
+size may be built.  This is used by the distrib/ tree and crunchgen
+when building ramdisks.  This sets/uses the following variables:
+
+DIST_LIB	The path of the library to build. [lib${LIB}_d.a]
+
+DIST_OBJS	The (sub)set of .o files to include in ${DIST_LIB}. [${OBJS}]
+
+DIST_CFLAGS	Additional flags for the C compiler and assembler.
