This script reimplements ldd in a way that should work for all
binary formats supported by the binutils installed on the host system.
An example: if you have a folder containing an x86_64 system, you can
invoke this script on a x86_32-host in order to determine all the libraries
required by a binary of the x86_64 target system.

=head1 NAME
slxldd - OpenSLX-script to determine the libraries required by any given
binary file.
=head1 SYNOPSIS
slxldd [options] file [...more files]
Options:
--help brief help message
--man show full documentation
--root-path=<string> path to the root folder for library search
--verbose show what's going on during execution
--version show version
=head1 OPTIONS

=item B<--help>
Prints a brief help message and exits.
=item B<--man>
Prints the manual page and exits.
=item B<--root-path=<string>>
Sets the root folder that is used when searching for libraries. In order to
collect the loader-settings, etc/ld.so.conf is read relative to this path and
all libraries are sought relative to this path, too (a.k.a. a virtual chroot).
Defaults to '/'.
=item B<--verbose>
Prints info about the files as they are being scanned.
=item B<--version>
Prints the version and exits.
