   - `bedtools/bedtools_intersect`: Allows one to screen for overlaps between two sets of genomic features (PR #94).
   - `bedtools/bedtools_sort`: Sorts a feature file (bed/gff/vcf) by chromosome and other criteria (PR #98).
   - `bedtools/bedtools_groupby`: Summarizes a dataset column based upon common column groupings. Akin to the SQL "group by" command (PR #123).

   - `bedtools/bedtools_bamtofastq`: Convert BAM alignments to FASTQ files (PR #101).
   - `bedtools/bedtools_bedtobam`: Converts genomic feature records (bed/gff/vcf) to BAM format (PR #111).
+  - `bedtools/bedtools_links`: Creates an HTML file with links to an instance of the UCSC Genome Browser for all features / intervals in a (bed/gff/vcf) file (PR #137).
