0.0.5
* Fixed regression with --verbose output being buffered. This means dropping the helpful error
message introduced in 0.0.4.
0.0.4

## Setup
To get up and running with Attic, follow the [Attic Quick
Start](https://attic-backup.org/quickstart.html) guide to create an Attic
repository on a local or remote host. Note that if you plan to run atticmatic
on a schedule with cron, and you encrypt your attic repository with a
passphrase instead of a key file, you'll need to set the `ATTIC_PASSPHRASE`
environment variable. See [attic's repository encryption
documentation](https://attic-backup.org/quickstart.html#encrypted-repos) for
more info.
If the repository is on a remote host, make sure that your local root user has
key-based ssh access to the desired user account on the remote host.
To install atticmatic, run the following command to download and install it:
sudo pip install --upgrade hg+https://torsion.org/hg/atticmatic
@ -47,24 +59,7 @@ Then copy the following configuration files:
sudo mkdir /etc/atticmatic/
sudo cp sample/config sample/excludes /etc/atticmatic/
Modify those files with your desired configuration, including the path to an
attic repository.
If you don't yet have an attic repository, then the first time you run
atticmatic, you'll get an error with information on how to create a repository
on a local or remote host.
And if the repository is on a remote host, make sure that your local root user
has key-based ssh access to the desired user account on the remote host.
It is recommended that you create your attic repository with keyfile
encryption, as passphrase-based encryption is less suited for automated
backups. If you do plan to run atticmatic on a schedule with cron, and you
encrypt your attic repository with a passphrase instead of a key file, you'll
need to set the `ATTIC_PASSPHRASE` environment variable. See [attic's
repository encryption
documentation](https://attic-backup.org/quickstart.html#encrypted-repos) for
more info.
Lastly, modify those files with your desired configuration.
