We moved the building of an initial entry `README.md` file functionality
form `bin/cvt-submission.sh` to a new `bin/gen-readme.sh` tool.
Add `bin/gen-readme.sh` VERSION "2.0.0 2025-06-16".
Update `bin/cvt-submission.sh` to ignore while running `chkentry(1)`,
any submission top level `REDAME.md` file.
Removed unused template file `template/entry/README_md`.
Changed `bin/cvt-submission.sh` allowed minimum `chkentry(1)` VERSION from "1.1.5"
to "2.0.5".
Changed `bin/cvt-submission.sh` VERSION from "2.0.5 2025-05-18"
to "2.1.0 2025-06-16".
Update sitemap.
Tested the above via `make gen_top_html timestamp` on macOS.
We improve `bin/add-dir.sh` by calling `make genpath` so
that the `.allyear` will be up to date.
Changed `bin/add-dir.sh` VERSION from "1.1.1 2024-07-28"
to "1.2 2024-08-09".
Checkpoint `bin/cvt-submission.sh`: a work in progress.
Added more files to `template/entry` in support of the
checkpoint of the `bin/cvt-submission.sh` tool.
Changed `bin/cvt-submission.sh` VERSION from "1.0.2 2024-08-05"
to "1.0.3 2024-08-09".
Performed `make www` to accomplish the above and to test under macOS.
