For most purposes this package is a standard Debian Perl Group package.
The aspect in which it is special is that some related modules are bundled
together with the package. So long as you have the appropriate tar balls
in the correct place you can build using dpkg-buildpackage as you would
normally.

If you have a fresh checkout from the git repository and you wish 
to download all the tarballs to build under dpkg-buildpackage, then from the
package root directory run:

    ./debian/update.sh update

To check for new updates drop the "update" argument. If you are building
under dpkg-buildpackage you need to tell the script about the 
alternative build directory so run

    DESTDIR=.. ./debian/update.sh update

There are a couple of important caveats about the update.sh script.
First of all when used in update mode it will DELETE the existing tarballs.
Secondly when you do update one of the components, the update.sh script 
will need to be updated. These limitations arise because it is 
a temporary work around until pkg-components (or even uscan) provides
something more substantial.

Note also that the binary copyright file is a merger of 
debian/components/copyright.in and debian/components/*/copyright.
Various Debian tools require a static file in debian/copyright.
If for some reason the generated copyright file changes
copy from debian/$PACKAGE.copyright to debian/copyright after a build.
