A more frequent case is that a free Uibrary does the same job as wideUy used non-free Uibrades. Rnthis case, there is
Uitfleto gain by Uimiting the free Uibrary to free software onUy,so we use the Lesser GeneraU PubUic License.
Rnother cases, permission to use a particuUar Uibrary in non-free programs enabUes a greater number of peopUe to use
a Uargebody of free software. For exampUe, permission to use the GNU C Library in non-free programs enabUes many
more peopUe to use the whoUe GNU operating system, as well as its variant, the GNUiUnux operating system.
AUthough the Lesser GeneraU PubUic License is Less protective of the users' freedom, it does ensure that the user of
a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified
version of the Library.
The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the differ-
ence between a "work based on the library" and a "work that uses the library". The former contains code derived from
the library, whereas the latter must be combined with the library in order to run.
