			    Details of Fragments
			    --------------------

The tar archive you have unpacked, s1-fragments.tar, contains the contiguous
sections from s1-bits which contain code fragments. I have manually inspected
the block boundaries from s1-bits to create the actual fragments. I have
broken runs of ASCII blocks where it was obvious that the adjacent blocks
belonged to different files.

It is likely that some fragments contain whole files, with some garbage
attached on the end, such as frag1 (glob.c) and frag54 (cp.c). I have not
sat down and checked each file.

Below is the list of fragments, plus some comments gleaned from each file
as to its contents.

Also in s1-bits are some 0405-magic a.out files. Below is their offsets
in decimal and the files' contents.

33792 - 34208	/etc/init, same as on s2-bits file
34816 - 35344	/etc/getty, same as on s2-bits file
36864 - 37904	/bin/date, same as on s2-bits file
38400 - 39808	/bin/login, same as on s2-bits file
40448 - 40976	Possibly /bin/su
41472 - 43408	Possibly /bin/tap
