'`basename $0`' needed for developer and/or maintainer builds

Usage: $0 [options]
       $0 --help

Searches the sources for build dependencies and makes sure these are
satisfied by installing any missing packages using \`sudo\`.  The list
of build dependencies may be larger than actually necessary for your
particular build scenario(s).  It covers everything you need to get
started with a clean repository checkout and pass a \`make distcheck\`
as well as some extras that we use to generate software metrics.

The following options are supported:

  -h, --help              display this message and exit
  --with-included-boost   assume that the included Boost sources will
                          be used (does not install any Boost library
                          packages).  See \``dirname $0`/tools/include-boost-src\`
                          on how to include Boost sources.

BUG: does not really search the sources
BUG: only supports \`apt-get\`
