!==========================================================================
!
! To build the LIBBZ2_NS library, edit the USER CUSTOMIZATION
! lines below to taste, then do
!	mms
! or
!	mmk
! if you use Matt's Make (free MMS-compatible make utility).
!
! In all other cases where you want to explicitly specify a makefile target,
! you have to specify your compiling environment, too. These are:
!
!	$ MMS/MACRO=(__ALPHA__=1)		! Alpha AXP, (DEC C)
!	$ MMS/MACRO=(__IA64__=1)		! IA64, (DEC C)
!	$ MMS/MACRO=(__DECC__=1)		! VAX, using DEC C
!	$ MMS/MACRO=(__FORCE_VAXC__=1)		! VAX, prefering VAXC over DECC
!	$ MMS/MACRO=(__VAXC__=1)		! VAX, where VAXC is default
!	$ MMS/MACRO=(__GNUC__=1)		! VAX, using GNU C
!

! To delete all .OBJ, .OLB, .EXE and .HLP files,
!	mms clean
