Hello maintainer,

While performing an archive wide checkbashisms (from the 'devscripts' package)
check I've found your package containing a /bin/sh script making use
of a bashism.

checkbashisms' output:

Not using bash (or a Debian Policy conformant shell interpreter which doesn't
provide such an extra feature) as /bin/sh is likely to lead to errors or
unexpected behaviours.
Please be aware that although bash is currently the default /bin/sh there was
a release goal for Lenny to make dash the default /bin/sh[1], and has been
proposed for squeeze as well[2].

If you want more information about dash as /bin/sh, you can read:
http://lists.debian.org/debian-release/2008/01/msg00189.html

For more information supporting this goal please refer to Debian Policy,
section 10.4, at:
http://www.debian.org/doc/debian-policy/ch-files.html#s-scripts

Hints about how to fix bashisms:
Sometimes these bugs are already fixed in Ubuntu, look at the PTS.
If not already fixed you can read:
https://wiki.ubuntu.com/DashAsBinSh

If you still don't know how to fix the bashisms don't hesitate to reply to
this email, or tag the bug as 'help'.
