+Thunderbird build environment prep for run-task,
+for use with comm-central derived repositories.
+
+This script is meant to run prior to run-task on repositories like
+comm-central that need to check out a copy of a mozilla repository
+in order to build.
+See bug 1491371 for background on why this is necessary.
+
+A project will have a file named ".gecko_rev.yml" in it's root. See the
+constant "GECKO_REV_CONF" if you want to change that. To download it, the
+script uses the project repository URL and the revision number.
+Those are defined in the environment variables:
+COMM_HEAD_REPOSITORY
+COMM_HEAD_REV
+
+.gecko_rev.yml has a structure like (for comm-central):
+```
+GECKO_BASE_REPOSITORY: https://hg.mozilla.org/mozilla-unified
+GECKO_HEAD_REPOSITORY: https://hg.mozilla.org/mozilla-central
+GECKO_HEAD_REF: default
+```
+or for branches:
+```
+GECKO_BASE_REPOSITORY: https://hg.mozilla.org/mozilla-unified
+GECKO_HEAD_REPOSITORY: https://hg.mozilla.org/releases/mozilla-beta
+GECKO_HEAD_REF: THUNDERBIRD_60_VERBRANCH
+GECKO_HEAD_REV: 6a830d12f15493a70b1192022c9985eba2139910
+
+Note about GECKO_HEAD_REV and GECKO_HEAD_REF:
+GECKO_HEAD_REF is a branch name or "default".
+GECKO_HEAD_REV is a revision hash.
