# Yes, we really are putting the firmware tarball into the source package.
# We want to supply the firmware in both source and binary form, to save users
# the trouble of all the cross compilation and Verilog synthesis, and the Alpha
# firmware is the same regardless of the host platform, so including the firmware
# tarball in the source package lets us simplify installation for the user.
