=head1 NAME
|
||||
|
||||
Alien::Package::Deb - an object that represents a deb package
|
||||
|
||||
=cut

package Alien::Package::Deb;

=head1 DESCRIPTION
|
||||
|
||||
This is an object class that represents a deb package. It is derived from
|
||||
Alien::Package.
|
||||
|
||||
=head1 FIELDS
|
||||
|
||||
=over 4
|
||||
|
||||
=item have_dpkg_deb
|
||||
|
||||
Set to a true value if dpkg-deb is available.
|
||||
|
||||
=item dirtrans
|
||||
|
||||
After the build stage, set to a hash reference of the directories we moved
|
||||
files from and to, so these moves can be reverted in the cleantree stage.
|
||||
|
||||
=item fixperms
|
||||
|
||||
If this is set to true, the generated debian/rules will run dh_fixperms.
|
||||

||||

||||
=head1 METHODS
|
||||
|
||||
=over 4
|
||||
|
||||
=item init
|
||||
|
||||
Sets have_dpkg_deb if dpkg-deb is in the path. I prefer to use dpkg-deb,
|
||||
if it is available since it is a lot more future-proof.
