Our usual license involves a single license fee, split into several payments over a few
years. For that single fee, you get source code and machine-readable internal
documentation, a year of support, and the right to sublicense binary copies with no per-
copy royalties. The front end can be used as part of any number of products, on any
number of architectures, with no additional fee. You can make copies of the source code
for internal use with no additional per-CPU fee.
