=head1 NAME

botch-y-u-b-d-transitive-essential - Find out why source packages are B-D transitive essential.

=head1 SYNOPSIS

=over

=item B<botch-y-u-b-d-transitive-essential> [options] I<architecture> I<Packages> I<Sources> [pkgname]

=back

=head1 DESCRIPTION

Find the reasons why source packages are B-D transitive essential.
Assumes that Architecture:all packages need not be bootstrapped.
Operates on the strong dependency graph.

An optional package name as the last argument limits the output to that
package.

=head1 OPTIONS

=over 4

=item B<-h, --help>

Display help.

=item B<-k, --keep>

Keep the temporary files

=item B<-T, --timers>

time all program executions

=item B<-o, --output=>I<DIR>

Output directory. Default is the current directory

=item B<-t, --tmp=>I<DIR>

Temporary directory. Default is created by mktemp(1)

=item B<-v, --verbose>

Be more verbose

=item B<-d, --debug>

Maximum verbosity

=item B<-D, --develop>

Execute tools from the source checkout instead of $PATH

=head1 EXAMPLE

To find out why src:sysvinit is b-d-transitive-essential, run:

 botch-y-u-b-d-transitive-essential amd64 Packages Sources sysvinit

Edges from installation sets to source packages (builds-from relationships) can
be hard to diagnose. You can use dose-ceve to create a graph that doesn't
condense binary packages to their installation sets. This has the disadvantage
that also non-strong dependencies are also included.
