These are the files that are VOS-specific:

ckermit.env         You may want to rename this, but this is what the code
                    and the documentation say.  Holds "environment variables"

cklcon.c            C-Kermit code modules
cklfio.c
ckltio.c
cklnet.c

ckldef.c            Utilty program used in build process
cklmak.cm           Build command macro, makes kermit.pm

cklker.bwr          Beware file
cklker.doc          VOS-specific documentation for C-Kermit
cklins.doc          Installation document

cklcvt.cm           Conversion command macro, stream to fixed
ckltxt.c            Hex-ify program
cklxtr.c            Un-hex program
cklxtr.cm           Un-hex command macro
ckltxt.doc          Note about hex format used by ckltxt and cklxtr

The following are hex formatted executables, unpack with cklxtr:

cklker.h86          C-Kermit for i860 processor
cklker.h68          C-Kermit for 680x0 processor
cklxtr.h86          Extraction program for i860 processor
cklxtr.h68          Extraction program for 680x0 processor

There is a file that showed up called ckcvos.h, which is not needed.

Assuming that the ckl*.* files go on a tape with the rest of the C-Kermit
sources, that's all you need.  The files that C-Kermit uses are all
mentioned in cklmak.cm, other than the header files.  VOS C-Kermit uses
the UNIX command processor (ckucmd, ckuu*, etc.), the script (ckuscr.c),
DIAL (ckudia.c) and charset (ckuxla.c) packages, and Wart (ckwart.c).  The
BOO files (ckbmkb.c and ckbunb.c) work on VOS as well, but are not
necessary for C-Kermit to build or work.
