#	Dump static symbols as well.
#	
#	Revision 1.17  1999/11/13 06:08:40  voas
#	Add some frameworks, factor.
#	
#	Revision 1.16  1999/09/13 18:18:58  carbon
#	Remove references to lltb
#	
#	Revision 1.15  1999/09/10 22:33:24  jacklin
#	Use "sh" syntax that zsh doesn't mind (and is still compatible with sh),
#	and explicitly name the shell as /bin/sh at the top of the file
#
#	Revision 1.14  1999/09/09 16:43:02  jiarocci
#	Make shell explicit for native builds.
#	
#	Revision 1.13  1999/09/01 16:58:26  carbon
#	(jji) Add parameter variable to Quickdraw rules.
#	
#	Revision 1.12  1999/08/31 19:48:02  rmikawa
#	Integrate the changes to ATS Unicode, Font Manager, and Quickdraw Text from
#	Sonata(b7) and update the Carbon projects to link against Quickdraw.framework
#	instead of libqd.dylib.
#
#	Revision 1.11  1999/08/25 21:02:16  carbon
#	CarbonPrinting --> Printing
#	
#	Revision 1.10  1999/08/13 15:23:25  danp
#	Oops. Had the wrong pathname for Nav. Fixing.
#
#	Revision 1.9  1999/08/13 15:13:54  danp
#	Modified so that it knows that colorpicker, nav services and commonpanels have moved.
#	
#	Revision 1.8  1999/07/30 23:31:26  gpuckett
#	a few more comments and some cleanup
#	
#	Revision 1.7  1999/07/30 23:06:34  gpuckett
#	script now also creates individual exp files for each library containing its exported symbols
#	
#	Revision 1.6  1999/07/22 22:33:40  carbon
#	Add AppleEvents framework and CommonPanels
#	
#
# This script automates the process of building a stub library to use when compiling carbon
# applications for the mach-o environment.  This script takes three parameters, the path name 
# of the carbon symbols export file, the path to the destination directory of the build output that
# the symbols are to be extracted from, and the path to the object directory where all output
# from the script will be written.  It is executed from the make file as follows:  
#
#				buildstublib $(OBJROOT)/CarbonCore.exp $(DSTROOT) $(OBJROOT)
#
#
# The script takes all exported symbols from the specified libraries, sorts them, then 
# produces the following files:
# 
# CarbonLib				The stub library representing all symbols currently implemented on X
# 
# CarbonLib.exp  		contains all symbols exported by the libraries that are part of the 
#						actual target export set specified in CarbonLib_410.exp
#
# CarbonLibExtras.exp	contains all symbols exported by the libraries that are not 
#				   		listed in CarbonLib_410.exp
#
# CarbonLibUnimplemented  Contains all symbols listed in CarbonLib_410.exp that are not 
#				   		yet implemented in (exported by) the libraries
#
# CarbonLibDuplicates.exp  contains all symbols exported by the libraries that are not 
#				   		listed in CarbonLib_410.exp
#
# CarbonStubLib.c 	 	C stub file from which CarbonLib had been created
#
# "libname".exp			There is a exp file containing all symbols for that particular library
