Third-party components

Lince2D uses open-source libraries under permissive licenses (MIT, Apache 2.0, BSD, ISC, zlib, Unicode, Boost), the interface fonts (SIL Open Font License 1.1 and Ubuntu Font Licence 1.0), the spell-checker dictionaries and the acadrust library (Mozilla Public License 2.0). Their copyright notices and the full text of each license are in THIRD_PARTY_NOTICES.txt (in Spanish, with the license texts in their original English), the same file shipped with the program and shown in About.

acadrust source code (MPL 2.0)

Lince2D reads and writes DWG and DXF with a modified version of acadrust by Hakan AK, distributed under the Mozilla Public License 2.0. As that license requires, the source code of the version used by Lince2D, with all its changes, is available at:

https://github.com/jac0161/acadrust/tree/cadfv

The MPL applies to the acadrust files; the rest of Lince2D is governed by its own license (what the MPL 2.0 calls a “Larger Work”).
