+Trimadap is a small tool to trim adapter sequences from Illumina data. It
+performs SSE2-SW between each read and each adapter sequence and identifies
+adapter sequences with a few heuristic rules which can be found in the
+ta_trim1() function in trimadap-mt.c. The default adapters it uses are included
+in illumina.txt. These are typical Illumina adapters from paired-end
+sequencing.
