# LICENSING NOTE:
#
# The upstream source, when downloaded from the main website (i.e.,
# %%{url}/data/giada-%%{version}-src.tar.gz), contains excerpts from the
# Steinberg VST 3 SDK, which has additional restrictions on top of the GPLv3
# that make it unsuitable for distribution in Fedora. See
# https://lists.fedoraproject.org/archives/list/legal@lists.fedoraproject.org/message/FMFIZU22AP36J3DOUVCXUPHQ3MNDN5P6/.
#
# These problematic components may be filtered from the upstream source archive
# using a script to produce a distributable source archive. At once point this
# package followed that approach. Now we use the GitHub release tarball; since
# the problematic components (vst3sdk and juce) are git submodules, they are
# not included in the automatically-generated release tarball.
#
# Note that this means Giada will *not* be built with VST3 support in Fedora.
# (The situation for VST2 is even worse, as it is available only under a
# proprietary license.)
#
# Additional git submodules are handled as follows:
#   • json: unbundled downstream
#   • geompp: unbundled downstream
#   • rtaudio: bundled, provided as an additional source, since it is a
#     giada-specific fork
#   • mcl-atomic-swapper: bundled, provided as an additional source; this is
#     managed under the same GitHub organization as giada, and does not yet
#     have its own releases.
#   • mcl-audio-buffer: bundled, provided as an additional source; this is
#     managed under the same GitHub organization as giada, and does not yet
#     have its own releases. More importantly, it is not header-only but does
#     not yet have a build system configuration, so we really cannot package it
#     separately.

# The entire source is GPLv3+, except:
#   - src/deps/rtaudio (i.e., the contents of Source1) is MIT, except:
#     * src/deps/rtaudio/include/soundcard.h is BSD

# RtAudio (https://github.com/thestk/rtaudio)
#
# This version is slightly forked, so it is not possible to build with the
# system copy of RtAudio. See
# https://giadamusic.com/forum/viewtopic.php?f=2&t=177, where upstream
# discusses the decision to maintain a forked copy of RtAudio in the Giada
# source tree.
#
# The version comes from “#define RTAUDIO_VERSION” in
# src/deps/rtaudio/RtAudio.h.
Provides:  bundled(rtaudio) = %{rtaudio_srcversion}
# ============================================================================

# ============================================================================
# mcl-audio-buffer (https://github.com/monocasual/mcl-audio-buffer/)
#
# Currently, this is effectively still a part of giada. It has never had a
# version or a release, and it has no build system of its own. Since it is not
# header-only (compare to geompp), this makes it impractical to package it as a
# stand-alone library. Therefore we must bundle it as a part of giada until and
# unless it grows into a full-fledged project of its own.
