## Installation
### Requirements

On a Debian-based host running at least Debian Stretch, you will need the
following packages:
- git (recommended for getting the source)
- python3
- python3-jinja2

### Manual installation

1.  Clone repo

        $ git clone https://forge.april.org/adminsys/spamotron
        $ cd spamotron
        $ chmod a+x mailing.py

2.  Try it

        $ ./mailing.py --help
        $ ./mailing.py -t test-recipients-data -b test-emailling --dry-run --verbose

## Input format

### CSV

The « to-file » is expected to be csv with the [default
dialect](https://docs.python.org/3/library/csv.html?highlight=csv#dialects-and-formatting-parameters)
(delimiter = `,` and char delimiter =`"`).

The first line declare columns headers. The `from` and `to` headers are
expected the be found. Headers are lower cased.

To avoid boring repetition it is possible to declare a default column value
using `:` in header. The default value is considered when the column is lacking,
not when the column is empty.

### Templates

The templates files are expected to be [jinja2
templates](https://jinja.palletsprojects.com/en/2.11.x/templates/). The csv
values are accessible using the column name, i.e. one can insert the recipient
address anywhere in template using `{{ to }}`.

Don't worry about escaping: HTML templates are auto escaped.
