-When updating src/net/base/registry_controlled_domains/effective_tld_names.dat:
-
-1. Obtain the new effective_tld_names.dat, probably by downloading
-   http://goo.gl/Ji2bB
-
-2. Remove whitespace from the ends of the lines.
-   You could possibly use something like:
-     sed -i -e "s/\s*$//g" \
-         src/net/base/registry_controlled_domains/effective_tld_names.dat
-
-3. Add the Chromium note back in just after the license at the top, and just
-   before '===BEGIN ICANN DOMAINS==='. Ensure there is an empty line above and
-   two empty lines below the note. The note should say:
-// Chromium note: this is based on Mozilla's file:
-//  http://mxr.mozilla.org/mozilla-central/source/netwerk/dns/effective_tld_names.dat?raw=1
-
-4. Build tld_cleanup (the "(net)" > "tld_cleanup" project)
-
-5. Run it (no arguments needed), typically from src/build/Release or
-   src/build/Debug. It will re-generate
-   src/net/base/registry_controlled_domains/effective_tld_names.gperf.
-
-6. Check in the updated effective_tld_names.dat, effective_tld_names.gperf
-
-Note that gperf is no longer used for effective_tld_names, but when building
-chromium the file effective_tld_names.gperf will be parsed by make_dafsa.py
-to generate the file effective_tld_names-inc.cc, which is included in
-registry_controlled_domain.cc
