Usage: ${myname} <tool> [option] <version>
  'tool' in one of:
    --gcc, --binutils, --glibc, --uClibc, --linux,
    --gdb, --dmalloc, --duma, --strace, --ltrace, --libelf
    --gmp, --mpfr

  Valid options for all tools:
    --experimental, -x
      mark the version as being experimental

    --obsolete, -o
      mark the version as being obsolete

  Valid mandatory 'option' for tool==linux is one and only 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
