+// TODO nf-core: The key words "MUST", "MUST NOT", "SHOULD", etc. are to be interpreted as described in RFC 2119 (https://tools.ietf.org/html/rfc2119).
+// TODO nf-core: A module file SHOULD only define input and output files as command-line parameters.
+//               All other parameters MUST be provided as a string i.e. "options.args"
+//               where "options" is a Groovy Map that MUST be provided in the "input:" section of the process.
+//               Any parameters that need to be evaluated in the context of a particular sample
+//               e.g. single-end/paired-end data MUST also be defined and evaluated appropriately.
+// TODO nf-core: Software that can be piped together SHOULD be added to separate module files
+//               unless there is a run-time, storage advantage in implementing in this way
+//               e.g. bwa mem | samtools view -B -T ref.fasta to output BAM instead of SAM.
+// TODO nf-core: Optional inputs are not currently supported by Nextflow. However, "fake files" MAY be used to work around this issue.
+
+// TODO nf-core: Process name MUST be all uppercase,
+//               "SOFTWARE" and (ideally) "TOOL" MUST be all one word separated by an "_".
