## cpptoml

Popcorn uses the [cpptoml](https://github.com/skystrife/cpptoml) library for

## GNU-EFI

Popcorn's UEFI bootloader initially used
[GNU-EFI](https://gnu-efi.sourceforge.net), and still uses one file (the linker
script for the bootloader) from that project. GNU-EFI claims to be released
under the BSD license. Again, I could not find its specific license file, so I
am reproducing a generic 3-clause BSD license (the most restrictive, so as not
to assume any extra rights that may not actually be granted) for it here:

## Intel EFI Application Toolkit

Popcorn's UEFI loader uses code from Intel's EFI Application toolkit. Relevant
code includes license statements at the top of each file.

## Waf

Popcorn's build system uses [Waf](https://waf.io/), which claims to be released
under the BSD license. I could not find its specific license file, so I am
reproducing a generic 3-clause BSD license (the most restrictive, so as not to
assume any extra rights that may not actually be granted) for it here:
