clingy 1.0.0

A tool to save attachments from plain text emails

Clingy lets you save attachments from plain text emails.

From the command line, you can use it like this:

```
clingy email1.txt email2.txt email3.txt
```

By default, the attachments will be saved into the current directory.
You can specify a different directory using `-d` or `--directory` like so,
and the directory will be created if it does not exist:

```
clingy email.txt -d out
```

You can save specific attachments using glob patterns (`-g` or `--glob`)
and regular expressions (`-r` or `--regex`):

```
clingy email.txt -g "*.txt"
clingy email.txt -r "^.+\.txt$\text{You can't use 'macro parameter character \#' in math mode}$")
```

The combo glob/regex matcher is also available for good measure:

```python
import clingy

clingy.match("foo.txt", glob="*.txt")
clingy.match("foo.txt", regex="\.txt$")
