Description: This project is the community, third-party TI Nspire emulator,
Texas Instruments' ARM-based series of graphing calculators.
It supports the emulation of Touchpad, CX and CX CAS calcs on
Android, iOS, Linux, Mac and Windows.

FAS Username: tc01

Why not in Fedora: firebird-emu is pure FOSS, but not only does it require TI's
proprietary operating system for the Nspire line of calculators, but also the
proprietary boot/base code blobs from the calculator itself. Thus as per the
emulator policy, since this package isn't functional without any proprietary
blobs, I believe this package still needs to be in RPM Fusion.

Note: upstream usually uses the name "firebird" for this package, but the name
"firebird" belongs to another package in Fedora, so I opted for "firebird-emu"
(as this name is also sometimes used by upstream). 

There is a potential for name conflicts. Currently the firebird package
installs a %{_sbindir}/firebird [1]. This package installs a
%{_bindir}/firebird. This doesn't cause a conflict per _se_, but if both are on
$PATH there's a potential for confusion. Should I rename the binary from
firebird -> firebird-emu as well?

As far as I can tell, the packages do not currently conflict in any other way.
