SYNOPSIS 

	'dpkg-buildpackage' , 'dpkg-genchanges' , 'debsign'

instructions (and 'debsign' for gpg package signing)
working with source (orig.tar.gz)
(using/creating .diff.gz, .dsc, .changes files)


<dutchfish> how to create a diff.gz out of an orig and changed version of a package?


<peterS> dutchfish: you have an unpacked version of the source tree that you've been hacking in?
and you have the orig.tar.gz in the parent directory?  then just call 

	dpkg-buildpackage -us -uc -S

<dutchfish> peterS, how to resign it?
<dutchfish> peterS, with my own gpg


<peterS> dutchfish: well, if you omit the -us -uc then it will sign the source and changes files.
alternatively you can use

        'debsign' from the devscripts package, after the fact

<peterS> dutchfish: if you want dpkg-buildpackage to know the right key to sign it with, 
you'll have to change the 'Maintainer' field in debian/control to the same name/address that
your gpg key advertises

<peterS> dutchfish: though debsign has an option for signing with any given key

<dutchfish> peterS, ok, the rest i figure out, thx very much

<dutchfish> peterS, if i understand it right, i just recreate changes with orig as reference, 
and sign it myself as package-mantainer, there are no changes on changes?

<peterS> dutchfish: use

		'dpkg-buildpackage -S' calls 'dpkg-source' 

to actually build the .diff.gz and .dsc files, and dpkg-genchanges to generate the .changes file. 
the .dsc and .changes files need to be gpg-signed if you want to upload to Debian

<peterS> dutchfish: if you want to sign the .dsc and .changes files as they are built, you just 

		call dpkg-buildpackage -S.  

if you want to sign them separately (for example, with a different key than is mentioned 
in the Maintainers line of debian/control), you pass -us -uc to dpkg-buildpackage so it doesn't sign, 
then later you can call debsign with the .changes file

<dutchfish> peterS, i am not ready for that, because i am not a mantainer, 
but want a quick fix wich i can distrubute to my own repos, its a sec fix for curent apache in etch
