provide trivial method to have debug symbol packages built in PPAs

[James Hunt]

Ubuntu is constantly attempting to attract new developers. As such, I think it would be a great idea to be able to have a very simple way to build not only a binary PPA package for consumption by all, but also correspnding debug packages.

This would help the new dev who has created a PPA and has started to build a community around their new package, since it will make debugging bug reports easier for them.

Crucial to this idea is documentation explaining:

1) How to enable the additional -dbg package build for their PPA.
2) How to install the debug package ("apt-get install mypackage-dbg").
3) How to run gdb and see the full source ("apt-get source mypackage && gdb /usr/bin/myapp core")

After a lot of hacking around, the best info I found to create debug packages in my PPA was from the debian wiki:

http://wiki.debian.org/DebugPackage

The key info:

1) Update your package to build a debug package alongside a stripped package:

$ pkg=mypackage
$ cd mypackage-source-directory
$ cat >>debian/rules<<EOT

.PHONY: override_dh_strip
override_dh_strip:
        dh_strip --dbg-package=${pkg}-dbg

override_dh_auto_install:
        dh_auto_install --destdir=debian/$pkg

override_dh_installdocs:
        dh_installdocs --link-doc=$pkg
EOT

2) Build a source package:

$ bzr bd -S

3) Upload to your PPA:

dput ppa:userid/ppa-name mypackage-<version>_source.changes
