+// This program reads an include file database.
+// The database should cover each self .c and .h file,
+//   but not files in /usr/include
+// The database consists of pairs of nonblank words, where the first word is
+//   the filename that needs to include the file named by the second word.
+// For each .c file, this program generates a fooIncludes.h file that
+//  the .c file may include to include all the needed files in the right order.
+// It also generates a foo.dep file to include in the makefile.
+// Finally it detects cycles, and can work with two files, an old and a new one.
+// To incrementally write out only needed files after a small change.
+//
+// Based on a suggestion by Roland Conybeare, algorithm suggested by Craig
+//  Chambers, written by David Ungar, 3/1/89.
+//  Added PREFIX, {DEP/INC}_DIR, smaller dep output  10/92  -Urs
+
+// Add something for precompiled headers
+
+// To handle different platforms, I am introducing a platform file.
+// The platform file contains lines like:
+// os = svr4
+//
+// Then, when processing the includeDB file, a token such as <os>
+// gets replaced by svr4. -- dmu 3/25/97
+
+// Modified to centralize Dependencies to speed up make -- dmu 5/97
