package makedep;
// 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.
//
// 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
