##Bundled code ahoy
#The following isn't in Fedora yet:
Provides:       bundled(FreeSurround)
Provides:       bundled(imgui) = 1.70
Provides:       bundled(cpp-argparse)
#Is this technically bundled code? Adding this just in case:
#https://github.com/AdmiralCurtiss/rangeset
Provides:       bundled(rangeset)
#soundtouch cannot be unbundled easily, as it requires compile time changes:
Provides:       bundled(soundtouch) = 2.1.2
#dolphin uses tests not included in upstream gtest (possibly unbundle later):
Provides:       bundled(gtest) = 1.9.0
#This is hard to unbundle and is unmaintainable with little benefit:
Provides:       bundled(glslang)
# Currently it doesn't build using upstream wxGTK, so just use the internal one
Provides:       bundled(wxGTK)

Gamecube) emulator, which supports full HD video with several enhancements such
as compatibility with all PC controllers, turbo speed, networked multi player,
and more.
Most games run perfectly or with minor bugs.
