=head1 NAME
Dpkg::Build::Types - track build types
=head1 DESCRIPTION
The Dpkg::Build::Types module is used by various tools to track and decide
what artifacts need to be built.
The build types are bit constants that are exported by default. Multiple
types can be ORed.
=head1 CONSTANTS
=over 4
=item BUILD_DEFAULT
This build is the default.
=item BUILD_SOURCE
This build includes source artifacts.
=item BUILD_ARCH_DEP
This build includes architecture dependent binary artifacts.
=item BUILD_ARCH_INDEP
This build includes architecture independent binary artifacts.
=item BUILD_BINARY
This build includes binary artifacts.
=item BUILD_FULL
This build includes source and binary artifacts.
