# developer convenience:
# - gosu and sudo are used by the scripting to make the image more convenient
#   to use.
# - locales and locales-all are required to set the locale.
# - minicom and screen are useful to see UART communication.
# - dc and time are requirements of Synopsys VCS.
# - software-properties-common is required to be able to install newer gcc versions.
