=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
=back
=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.
