# This is a "default" Cromwell example that is intended for you you to start with
# and edit for your needs. Specifically, you will be interested to customize
# the configuration based on your preferred backend (see the backends section
# below in the file). For backend-specific examples for you to copy paste here,
# please see the cromwell.backend.examples folder in the repository. The files
# there also include links to online documentation (if it exists)

# This line is required. It pulls in default overrides from the embedded cromwell
# `reference.conf` (in core/src/main/resources) needed for proper performance of cromwell.
