# System development

## Create build environment

	localcowbuilder-create jessie


## Refresh build environment

	localcowbuilder-update jessie


## Build package

Minimal steps involved in building a new package:

Refresh copyright file:

	debian/rules pre-build DEB_MAINTAINER_MODE=1; debian/rules clean DEB_MAINTAINER_MODE=1

Resolve changelog from git commits:

	gbp dch -a

Finalize changelog
(manually merge/drop items to reflect only product):

	dch -r

Build in clean chroot and tag as final:

	localgitcowdebuild sid --git-tag

Compare built binaries against previous ones
(in MC shell):

	debdiff --controlfiles ALL --wl %f %D/%F | less

Check lintian warnings/errors:

	lintian *.changes

Rebuild source-only package
(to save bandwidth uploading, and for official rebuild):

	localgitcowdebuild sid -S

Sign and upload:

	debsign %f && dput %f


## Backport package for main architecture

	localcowdebuild jessie -sa


## Backport package for secondary architecture

	localcowdebuild jessie-ia32 -b
