+## Process the output of makedepend.
+## Copyright (c) 1994 Amdahl Corporation.
+## Written by Ben Wing, December 1994.
+
+## This file is used as part of 'make depend', to produce the
+## dependency list for src/Makefile.in.in.
+
+## Unfortunately, makedepend (at least the one that comes as part
+## of Open Windows under Solaris) is stupid and doesn't follow the
+## documented behavior.  So we have to force the definitions of
+## certain options through -D flags (even though it's supposed to
+## pick this up), and post-process the output to get rid of stuff
+## we don't want.
+
+## The sed stage gets rid of include files in other directories,
+## except for lwlib.h (makedepend puts system include files in,
+## which is pretty stupid).  We also get rid of some standard
+## include files that are in every or pretty much every file
+## and where changes in those files don't usually merit
+## recompilation of everything.  Finally, we eliminate entirely
+## the dependencies for some files (such as unex*.c) that get
+## screwed up by makedepend.  We just put those in by hand at
+## the top of the dependency list.
+
+## The awk stage puts one dependency per line.  Then we pass
+## the result through sort and uniq (makedepend is supposed
+## to not put in duplicate dependencies, but it does so
+## occasionally).
+
+## After running 'make depend', verify that the output (in
+## depend.out) is reasonable and then replace the stuff in
+## Makefile.in.in marked "generated by 'make depend'".
