ReleaseEngineering/How To/Update TryChooser

We need to keep the try syntax chooser webpage located at http://trychooser.pub.build.mozilla.org/ up to date so developers will continue to use it and we benefit from the lowered build/test load.

To keep the site up to date, check out the tools repo and update index.html with new test/talos suite names - be sure to change both the value and the label. Eg:

<li><label><input type="checkbox" name="talos_suite" value="SUITE_NAME">SUITE_NAME</label></li>

Once you've landed your patch to the webpages, push the change to the releng web cluster, same as for any other push: login to relengwebadm as root, go to /data/releng/src/trychooser, and run ./update $REV.

# root@relengwebadm.private.scl3.mozilla.com
# Get your REV from hg.
REV=753b5928284f
cd /data/releng/src/trychooser
./update $REV.
