A slight echo on the Interlisp file package (partly response to earlier note
on problems using MAKEFILE, and losing a bunch of user-entered properties.

Rule 1.  Users never call MAKEFILE (in 9 years of Interlisp hacking, I've
probably called it half a dozen times).

So how do you make files?  I mainly use two functions:
CLEANUP()     or CLEANUP(file1 file2 ...)   Former does all files containing
	modifications, latter only named files.  The first thing CLEANUP does
	is call UPDATEFILES, which is also called by:
FILES?()	Reports the files which need action to have up to date
	source, compiled and hardcopies, also calls UPDATEFILES, which will
	engage you in a dialog asking you the location of every "new" object.

Most of the ways to define or modify objects are "noticed" by the file
package (e.g. the structure editor [DF, EF, DV ...], SETQ, PUTPROP, etc which
YOU type at top level).  When an object is noticed as modified, either the
file(s) containing it are marked as needing a remake, or it gets noted as
something to ask you about later.  You can write functions which play the
game by calling MARKASCHANGED as appropriate.

Two global variables interact with details of the process:
RECOMPILEDEFAULT  usually EXPRS or CHANGES.  I prefer the former, but CHANGES
	has been the default in Interlisp-D because EXPRS didn't work before 
	Intermezzo.
CLEANUPOPTIONS	My setting is usually (RC STF LIST) which means as part of
cleanup, recompile, with compiler flags STF (F means forget source from in
core, filepkg will automagically retrieve it if you edit, etc), and make a
new hardcopy LISTing.

For real fun with filepkg and integration with other tools, try
MASTERSCOPE(ANALYZE ALL ON file1)
MASTERSCOPE(EDIT WHERE ANY CALLS FOO)
CLEANUP()
