this archive is not being used by itself,
the only program needed from it (cv) has been extracted, is listed below

--- our own or other sources without upstream, to be audited by you:

cv_orig/              - Minix-vmd specific variant of cv for ackpack
cv/                   - the above, edited by us
elf2aout.c.for_tinycc - as the name says
elf.h                 - elf definitions (from musl C library, specifically
                        allowed to be used without attribution, otherwise
                        reasonably non-copyrightable)
mkproto.c             - modified to create reproducible proto files
                        (NOTE not intended for cross-use with device files)
sltar.c               - a tar version which creates reproducible archives
