This is the source for the spell program and utilities.  It is taken
from UNIX PC Document Preparation 3.5.  It was not recompiled for
Document Preparation 3.51; the executable files were taken directly
from Doc Prep 3.5.  The executables used in Doc Prep 3.51 are found
in spell.bin.

Spell requires the deroff program.  
Please note that the deroff program from this source was not used
for Doc Prep 3.51; instead, source for deroff was taken from AT&T
Documenter's Workbench 2.0, and is found in 
../DWB.II/subndx.d/deroff.c.  When installing deroff, link
/usr/lib/dwb/deroff to /usr/bin/deroff in order for spell
to work properly.

Put spell in /usr/bin; put compress, hashcheck,
hashmake, hlista, hlistb, spellin, spellprog, hstop, spellhist in
/usr/lib/spell directory. 
Owner and group should be bin for all files
Set permission 755 for spell, compress, hashcheck, hashmake, spellin,
