usage_msg="\
Usage: `basename ${0}` [--no-docs]

Install the dependencies needed for building VirtualBox on a Linux
system.  Initial support for Enterprise Linux derivatives, additional
distributions will be added as needed.  There are no plans to add
support for or to accept patches for distributions we do not package.
The \`--no-docs\' parameter is used to prevent installation of TeX
packages.  Installing TeX is not supported on EL5, so the flag is
ignored there."

# To repeat: there are no plans to add support for or to accept patches
# for distributions we do bot package.
