=head1 NAME
botch-calcportsmetric - calculate source package importance
=head1 SYNOPSIS
=over
=item B<botch-calcportsmetric> [options] I<strongsrcgraph.xml> I<closuresrcgraph.xml>
=back
=head1 DESCRIPTION
Calculate a metric for source package importance based on how many source
packages (minimum and maximum) become compilable in a bootstrapping scenario
through the compilability of a given source package.
=head1 OPTIONS
=over 4
=item B<-h, --help>
show this help message and exit
=item B<--online>
Retrieve popcon results for source packages
=item B<-v, --verbose>
print additional information
=back
=head1 EXAMPLE
Calculate source package importance:
zcat packages_amd64.gz | grep-dctrl -FArchitecture all > available
botch-create_graph --deb-native-arch=amd64 --available=available --strongtype packages sources > strongbuildgraph.xml
botch-buildgraph2srcgraph --deb-native-arch=amd64 strongbuildgraph.xml packages sources > strongsrcgraph.xml
botch-create_graph --deb-native-arch=amd64 --available=available --closuretype packages sources > closurebuildgraph.xml
botch-buildgraph2srcgraph --deb-native-arch=amd64 closurebuildgraph.xml packages sources > closuresrcgraph.xml
botch-calcportsmetric --online strongsrcgraph.xml closuresrcgraph.xml > importance_metric_noall.txt
