This directory contains source for UNIX PC DOCUMENT PREPARATION 3.51,
troff, and associated utilities.  Docprep 3.51 source was not built
in one piece; it is derived from two sources, the AT&T Documenter's
Workbench 2.0 and UNIX PC DOCUMENT PREPARATION 3.5.  Troff, nroff,
and several associated utilities from Documenter's Workbench 2.0 are
found in the DWB.II directory.  
Because troff is not used, the DWB.II/roff.d/troff.d directory
from the original DWB 2.0 has not been included.  The
roff.mk makefile in DWB.II/roff.d has not been modified to remove
the troff-related commands.
Due to changes made to source, not
all make files will work to install programs and
files.  Where extensive changes were made to a makefile, or a new
directory added a higher-level
make file may not know about a new makefile that does work.  
Any problems with make files are explained in README files in
the appropriate directories.

Source for DOC PREP 3.51 can be found in these directories:
DWB.II, col, dpcommand, nrffilters, spell, and tabset.

Check install/docprep3.51/Files for the list of files
actually used by DOC PREP 3.51.
