# Licensing terms of Chawan Chawan itself is dedicated to the public domain. However, it contains and depends on projects with different licensing terms. This document attempts to list licensing terms of projects included in the Chawan repository. Note that Chawan is dynamically linked against your copy of libcurl, (on Linux) libseccomp, your C library, and if exists, your termcap library. For licensing terms of these, please consult the appropriate library's documentation. Also, Chawan is statically linked to the Nim standard library. At the time of writing, (i.e. as of Nim 2.0.8) this is the MIT license (same terms as the vendored Punycode library). Table of contents: * [Chawan](#chawan) * [QuickJS](#quickjs) * [Punycode library](#punycode-library) * [STB image](#stb-image) * [JebP](#jebp) ## Chawan ``` This is free and unencumbered software released into the public domain.
