+#  Environment variables
+#   - RUNNER - datalad or reproman (default: reproman)
+#   - Options to  reproman run  invocation
+#     - RM_ORC - orchestrator to use (default: datalad-pair-run)
+#     - RM_RESOURCE - resource to use (default: local)
+#     - RM_SUBMITTED - submitter to use (default: local)
+#   - BIDS_APPS - if set -- ,-separated list of apps to consider (out of
+#     mriqc and fmriprep ATM)
+#   - FS_LICENSE - filename or content of the license for freesurfer
+#   - CONTAINERS_REPO - an alternative (could be local) location for containers
+#                       repository.
+#     Make sure that you have got the images for specific versions we freeze to below:
+#       datalad get images/bids/bids-mriqc--0.15.0.sing images/bids/bids-fmriprep--1.4.1.sing
+#
+#   - INPUT_DATASET_REPO - an alternative (could be local) location for input
+#                       BIDS dataset
+#
+#  Note that if FS_LICENSE does not point to a file and is not empty, it would
+#  assume to contain the license content.  If you are not interested in running
+#  only MRIQC, just set it to some bogus value.
+#  So to run only mriqc if you don't have freesurfer license, do
+#  BIDS_APPS=mriqc FS_LICENSE=bogus ...
