SyntaxError in line 14 of Snakefile

[Blosberg]

Thanks for creating this package. I've followed instructions here through to step 4, at which point when I try to run the workflow I get the following:

$snakemake --cores all -n
SyntaxError in line 14 of /path/to/workflow/Snakefile:
invalid syntax (Snakefile, line 14)

Line 14 being the config: line in the following context

...
module rna_seq_star_deseq2:
    snakefile:
        /path/to/workflow/Snakefile
    config:
        config
...

I can't see anything wrong with my config file. As far as I'm aware the packages from snakemake/deploy are all there. I also undid all of my project-specific entry data to the files in config and set them back to being identical to the original template. Do you have any idea where this is coming from?
