You wait ages for somebody to develop a bioinformatics tool called 'Kraken' and then three come along at once

I recently wrote about the growing problem of duplicated names for bioinformatics tools. A couple of weeks ago, Stephen Turner (@genetics_blog) pointed out another case:

So Kraken is either a universal genomic coordinate translator for comparative genomics, or a tool for ultrafast metagenomic sequence classification using exact alignments, or even a set of tools for quality control and analysis of high-throughput sequence data. The latter publication is from 2013, and the other two are from this year (2014).

I feel sorry for the poor Grad Student who is going to lose a day of their life trying to install one of these tools before realizing that they have been installing the wrong Kraken.
