License Notes

The Trusster Open Source License (TOSL) is a derivation of the Sleepycat License. The one significant difference is that where the Sleepycat License says:

  The source code must either be included in the distribution or be
  available for no more than the cost of distribution plus a nominal
  fee, and must be freely redistributable under reasonable conditions.

TOSL is somewhat more specific:

  The source code must either be included in the distribution or be
  available in a timely fashion for no more than the cost of
  distribution plus a nominal fee, and must be freely redistributable
  under reasonable and no more restrictive conditions.

While the Sleepycat License is considered to be a free, GPL-compatible license, but TOSL is GPL-incompatible because of the addition of the "no more restrictive" language.
