 Usage: ${myname} <tool> [option] <version>

   'tool' in one of:

     --gcc, --tcc, --binutils, --glibc, --uClibc, --linux, --cygwin

   Options:

     --experimental, -x

       mark the version as being experimental

   Valid mandatory 'option' for tool==gcc is one of:

     --core, --final

   Valid mandatory 'option' for tool==linux is one of:

     --install, --sanitised, --copy

   'version' is a valid version for the specified tool.

   Examples:

     add version 2.6.19.2 to linux kernel install method:

       ${myname} --linux --install 2.6.19.2

     add versions 2.3.5 and 2.3.6 to glibc:

       ${myname} --glibc 2.3.5 2.3.6
