Add GPL-2-or-later license headers to the DOS utility source files and
document the purpose and local dependencies of each C, header and assembler
file.
Preserve the original Martin Stover copyright attribution for the historic
MARS-NWE utility sources, including files that did not previously carry an
explicit header but are part of the original tool set. Add Mario Fetka as the
2026 copyright holder for the current maintenance work, and use Mario-only
headers for files without original Martin Stover ownership.
Also add a root-level COPYING file containing the GPL-2 license text.
Update the DOS utilities and test suite with the current Novell comparison
state.
Validated/updated tool behavior:
- improve CREATOR output by showing Novell-style attribute and rights masks
- extend FLAGDIR handling with old NCP22 directory attribute read/write
fallback paths
- expand NDIR Novell-style formatting, filtering, /SUB handling, date output,
DI/RI attribute display and richer metadata collection
- adjust REVOKE output/grammar, recursive /SUBDIRECTORIES behavior and trustee
update/delete paths to better match Novell tools
- adjust SLIST header/output behavior for logged-in and logged-out cases
- update README status to reflect the currently green/tested tools
Test-suite changes:
- add/refresh Novell comparison tests for CREATOR, NDIR, REVOKE and SLIST
- update NCOPY tests and collection scripts for the current investigation state
- refresh per-tool README files and top-level test documentation
- keep MAP documented as still separately open
NCOPY:
- add the current NCOPY implementation and experimental NCP74/server-side-copy
scaffolding
- build ncopy.c so it stays compile-tested
- keep NCOPY disabled in the NET multicall dispatch for now because the
server-side-copy/open-handle path is still unsafe and needs further analysis
Build:
- include ncopy.c in the DOS utility build
- drop the temporary MARS_DOSUTILS_VERSION define wiring from CMake
