This `accept.py` also serves as an example for a module accept
accompanying the script `filter.py`.

Avoid an exception later in function snapshot.

The field name was incorrect since commit 055c0755.

The bug was introduced in commit b3615f59.

Following modifications of `CMakeLists.txt` files.

With `target_sources` rather than referring to their path from another
directory.

It was difficult to find the `CMakeLists.txt` that controlled the the
compilation of a given file from the message of a compilation error.

This did not produce an error because the mod files are also in
`${CMAKE_CURRENT_BINARY_DIR}`.

Since `NR_util` has been integrated into Jumble.

But reading from them is not here yet.

Needed by test `Set_max_speed_degenerate`.

Because the program `test_set_max_speed` in tests `Set_max_speed` and
`Set_max_speed_noise` uses the results of program
`test_get_1_outerm`. `test_set_max_speed` opens an SHPC with
`shpc_open`, so it needs ishape_last.txt.

Since `shpc_open` is called by all processes, reading d0 and
`ishape_last` in `shpc_open` implies that we do not broadcast d0 and
`ishape_last`.

Store `ishape_last` and first date in components of derived type
shpc. We then remove arguments `d_init` and `ishape_last` of procedures
`read_snapshot` and `get_snapshot`.

Preparing for components `ishape_last` and `d_init` of type shpc.

It was confusing to mix opening an SHPC with broadcasting some part of
the resulting shpc variable.

By explicit formatting.

We are reverting commit e48b7f7e. I think I did not really appreciate
then that the number of days since 1950-1-1 is another date index. It
is clearer to use just one date index, which is in the dbf files. So,
in effect, we replace everywhere the old 0-based date index k by `k -
d_init`. Note that we no longer need argument `d_init` for procedure
`dispatch_snapshot` and we no longer need to write `d_init` to file
`node_id_param.json`. Note also that the value of every node index
changes by the amount `d_init * e_overestim`.

Update dbf files with field date instead of `days_1950`.

We need this since `inst_eddies_Aviso.py` imports `inst_eddies` which
is in the binary directory.

Rather than with Unix-specific chmod command. This requires CMake `3.20`.

Following convention for the source of `configure_file`. See Scott
2021 k1077, § 19.7.

Use a symbolic link instead of appending to `sys.path`. THe motivation
is that in the Python interpreter, the following statements failed
before the present commit:

```python
import sys
sys.path.append("/path/to/Detection_eddies/Inst_eddies/Analysis")
import plot_eddy_contours
```

`sys.path[0]` then does not contain
`/path/to/Detection_eddies/Inst_eddies/Analysis` so
`plot_eddy_contours` could not find `util_eddies`.

When there are more than 3 input files. We recover the convenience of
commit b34b85a8, with the underlying generality of commit d365e754.
