Plain text feature files will be compressed to zipped, pickled datastructures
that load must faster.
These methods evolve, sometimes in incompatible ways.
In those cases we bump this version number.
That will cause TF not to use compressed files that have been compressed by
older, incompatible methods.
Instead, TF will produce freshly compressed data files.
The compressed data files are stored in a directory `.tf/{PVN}/` next
to the original `tf` files, where `{PVN}` is the package version number.

Text-Fabric offers and API to TF apps.
This is the version that the current Text-Fabric offers to its apps.
Apps require a version. The provided version and the required version must
match exactly in order to get a working system.
We do not aim for backward compatibility, since it is very easy to obtain a new version
of an app.
When Text-Fabric loads a TF app, it will check the api version that the app requires
against this version.
App requirement higher than TF API version
: The user is advised to upgrade Text-Fabric, or, alternatively,
select an older version of the app
App requirement lower than TF API version
: The user is advised to obtain a newer version of the app, or alternatively,
downgrade Text-Fabric
