The license starts with this preamble, and then continues with the
ordinary LGPLv2. Note that this license is more permissive than the
standard LGPL, so this is not a question about whether this is free
software or not.
License: LPGLv2 with exceptions
is perfectly descriptive and valid. Folks will have to look at the
license file for details anyway. For example, see also qt4 packaging
that uses something similar.
