Place email text files here for them to be automatically imported.
The directory naming convention is data/import/<class-type>/<class-label>.
For the built-in email type with business and personal labels,
the import directory must include the type and the fully qualified class label:
data/import/email/email.businessdata/import/email/email.personal
For raw, un-annotated data, use the root class label without specifying a subclass:
data/import/email/email
Re-use directories for multiple annotations of the same training data with different labels by using symlinks:
$ cd email
$ ln -s email.business email.business.trips
$ ln -s email.personal email.personal.family
