isbntools fail under Python 3.7

[workflowsguy]

When running any of the isbntools commands from the command line with Python 3.7 installed, an error message like this is displayed:

Traceback (most recent call last):
  File "/usr/local/bin/to_isbn13", line 7, in <module>
    from isbntools.bin.to_isbn13 import main
  File "/usr/local/lib/python3.7/site-packages/isbntools/bin/to_isbn13.py", line 5, in <module>
    from ..app import quiet_errors, to_isbn13

    from ._initapp import config, registry, CONF_PATH, CACHE_FILE

Thanks. This is a bug!

In order to fix your installation create a folder ~\.isbntools and a configuration file (inside this folder) called isbntools.conf with the following content:

[MISC]
REN_FORMAT={firstAuthorLastName}{year}{title}{isbn}
DEBUG=False

[SYS]
URLOPEN_TIMEOUT=10
THREADS_TIMEOUT=12

[SERVICES]
DEFAULT_SERVICE=goob
VIAS_MERGE=parallel

This issue was solved with release isbntools-4.3.16.
