# This script is used by the main "builddeps" script in libreboot src/meta archives.
# The reason it is seperated here is so that flashrom can be built separately aswell.

# To build flashrom, you will need the dependencies in "builddeb".
# Run it, or adapt it if you do not use an "apt-get" distro.
