Gee, seems that ShrinkIt has caused quite a stir... hmmm...

I'm about to start seeding people with delta copies of ShrinkIt 1.0 -- I got
the extra memory routines done last night (this morning?).  ShrinkIt currently
has an 18.1k buffer space for output data VS. the 9.7k output buffer in 0.95
-- when I add the extra filename business (so you can select up to 253 files
for an option) the buffer space should increase to slightly over 22k. 
Increasing the buffer size decreases the unpacking/packing time by about 10-15
seconds on a fairly full 3,5" disk, and makes it possible for me to consider
adding disk swapping in a future version.

I'm going to have one other problem, though -- I'm very busy here at college
right now, and probably am not going to have time to write *GOOD*
documentation for ShrinkIt.  Is there anyone out there who would like to do
this for me?  You'd just have to write the text and mail it to me -- I'd mail
you (or send you, whichever) a delta copy of shrinkit 1.0 to fiddle with.

I finished the Binary II unpacking in ShrinkIt last night -- it's able to do
selective extraction for a Binary II file, just like the NuFX archives.  If
the file in question is part of a bundled subdirectory, the proper
subdirectories to complete the pathname are automatically created.  If the
file in question conflicts with an existing file and you rename the file,
giving it a new partial pathname with new subdirectories, the additional
subdirectories are created as well.

I'm considering removing the virus detectors from ShrinkIt -- the reason being
that they can be triggered too easily.  The virus detectors work on the
principle of knowing what the full or partial pathname provided at $280 is. 
Unfortunately, sometimes there is no default pathname provided at $280 by a
particular selector, in which case I'm unable to "find" the SYS file, shrinkit
and examine it for changes.  Should I leave the detectors in, or take them
out?
