### Description of feature Currently we end up with lines like this: ``` @PG PN:align_trim ID:align_trim VN:1.0.1 CL:/opt/conda/bin/align_trim --samfile test.sorted.bam --output test.primertrimmed.bam --report test.align_trim_report.tsv --amp-depth-report test.amp_depth_report.tsv --normalise 200 primer.bed ``` We should modify this to be a little more consistent with how users will expect it, outputting e.g. ``` @PG PN:align_trim ID:align_trim VN:1.0.1 CL:align_trim --samfile test.sorted.bam --output test.primertrimmed.bam --report test.align_trim_report.tsv --amp-depth-report test.amp_depth_report.tsv --normalise 200 primer.bed ```
