**What it does**

This tool joins paired end FASTQ reads from two separate files into a
single read in one file.  The join is performed using sequence
identifiers, allowing the two files to contain differing ordering.  If
a sequence identifier does not appear in both files, it is excluded
from the output.

-----

**Input formats**

Both old and new (from recent Illumina software) style FASTQ headers
are supported.  The following example uses the "old" style.

Left-hand Read::

    @HWI-EAS91_1_30788AAXX:7:21:1542:1758/1
    GTCAATTGTACTGGTCAATACTAAAAGAATAGGATC
    +HWI-EAS91_1_30788AAXX:7:21:1542:1758/1
    hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

Right-hand Read::

    @HWI-EAS91_1_30788AAXX:7:21:1542:1758/2
    GCTCCTAGCATCTGGAGTCTCTATCACCTGAGCCCA
    +HWI-EAS91_1_30788AAXX:7:21:1542:1758/2
    hhhhhhhhhhhhhhhhhhhhhhhh`hfhhVZSWehR

-----

**Output**

A multiple-fastq file, for example::

    @HWI-EAS91_1_30788AAXX:7:21:1542:1758
    GTCAATTGTACTGGTCAATACTAAAAGAATAGGATCGCTCCTAGCATCTGGAGTCTCTATCACCTGAGCCCA
    +HWI-EAS91_1_30788AAXX:7:21:1542:1758
    hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh`hfhhVZSWehR

------

**The "new" style**

Recent Illumina FASTQ headers are structured as follows::

  @COORDS FLAGS
  COORDS = INSTRUMENT:RUN_#:FLOWCELL_ID:LANE:TILE:X:Y
  FLAGS = READ:IS_FILTERED:CONTROL_NUMBER:INDEX_SEQUENCE

where the whitespace character between COORDS and FLAGS can be either
a space or a tab.
