Convert QSEQ to FASTQ

I have written a PERL script to convert Illumina QSEQ or Export file to FASTQ.
In order to run it, you will need PERL installed.
type in the command: "perl illumina2fastq" to get the help.
typical command:
perl illumina2fastq -i input_qseq.txt -o output.fastq

The script is as below (Please save the script as "illumina2fastq"):
