+  summary: 'The FASTX-Toolkit is a collection of command line tools for
+    Short-Reads FASTA/FASTQ files preprocessing.
+
+    Next-Generation sequencing machines usually produce FASTA or FASTQ files,
+    containing multiple short-reads sequences (possibly with quality
+    information).
+
+    The main processing of such FASTA/FASTQ files is mapping (aka aligning) the
+    sequences to reference genomes or other databases using specialized
+    programs. Example of such mapping programs are: Blat, SHRiMP, LastZ, MAQ
+    and many many others.
+
+    However, it is sometimes more productive to preprocess the FASTA/FASTQ files
+    before mapping the sequences to the genome - manipulating the sequences to
+    produce better mapping results.
+
+    The FASTX-Toolkit tools perform some of these preprocessing tasks.'
