 // 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
