-What is the "Bot Update" step?
-==============================
-
-This step ensures that the source checkout on the bot (e.g. Chromium's src/ and
-its dependencies) is checked out in a consistent state. This means that all of
-the necessary repositories are checked out, no extra repositories are checked
-out, and no locally modified files are present.
-
-These actions used to be taken care of by the "gclient revert" and "update"
-steps. However, those steps are known to be buggy and occasionally flaky. This
-step has two main advantages over them:
-  * it only operates in Git, so the logic can be clearer and cleaner; and
-  * it is a slave-side script, so its behavior can be modified without
-    restarting the master.
-
-Why Git, you ask? Because that is the direction that the Chromium project is
-heading. This step is an integral part of the transition from using the SVN repo
-at chrome/trunk/src to using the Git repo src.git. Please pardon the dust while
-we fully convert everything to Git. This message will get out of your way
-eventually, and the waterfall will be a happier place because of it.
-
-This step can be activated or deactivated independently on every builder on
-every master. When it is active, the "gclient revert" and "update" steps become
-no-ops. When it is inactive, it prints this message, cleans up after itself, and
-lets everything else continue as though nothing has changed. Eventually, when
-everything is stable enough, this step will replace them entirely.
