Hi,

New version Tophat 2.0.6 is ready for upload. I used
debian/get-orig-source to make sure SeqAn was removed correctly.

This is a bug fix realease. Upstream changelog:
TopHat 2.0.6 release 11/02/2012
Version 2.0.6 is a maintenance release addressing some issues found in
the 2.0.5 release:
- corrected the indel finding algorithm that caused segmentation fault
in certain cases (long_spanning_reads and tophat_reports)
- fixed the Bowtie version checking code, adding support for newer,
non-beta Bowtie2 versions
- several minor fixes in the fusion alignment algorithm
- fixed an incompatibility issue with Python versions older than 2.6
(restoring Python 2.4 compatibility)
- fixed and improved the resuming option (-R/--resume) to better
handle various failure/resume situations
- added a warning about Bowtie1 and Bowtie2 index files in the same
directory (causing trouble if they were built for different genomic
sequences)

Thanks,
Carlos
