Re:   BU.LBR

BU is a new "Backup Utility" program that will allow hard disk owners 
to quickly back up their system onto floppies.  It was originally based 
on BAK25KP, but has been almost completely re-written.  It is not 
hardware specific (except for the clear screen sequence, but that is 
easily patched without reassembly) and is set up to copy files in 
disk/user/alphabetical order and so works nicely on ZCPR/ZCPR2/ZCPR3 
systems, but will work on a normal CP/M 2.2 system as well.  Not sure 
it will work under 3.0 as it chases the DPH/DPB blocks to determine 
disk capacity/blocking size/etc.  May not work under CP/M v1.4 either, 
but should work fine on all CP/M v2.2 systems.
