tools/build.py -i .header -I .footer
Besides this configuration options, the script will automatically read these
environment variables. If the host system proxy parameters match the ones
going to be used, no other input parameters will be needed. These are the
variables that will be picked up from the user env:
::
HTTP_PROXY, http_proxy, HTTPS_PROXY, https_proxy, FTP_PROXY,
ftp_proxy, NO_PROXY, no_proxy
Also these variables could be overwritten using ``--build-args``, which have
precedence.
