+# This script builds tar, rpm, and deb packages for a new release.  The
+# packages are created in the release/ directory (which is created if it
+# does not exist).
+#
+# There's only one command line option: VERISON.  It must be newer than
+# the last version in the Changelog; see check_version().  Do not include
+# a leading 'v', just `build-packages 1.0.8' for example.
+#
+# These environment variables control what the script does:
+#   CHECK=0|1     - Do (not) check the branch, version, etc.
+#   UPDATE=0|1    - Do (not) update changelogs, versions, etc.
+#   BUILD=0|1     - Do (not) build any packages
+#   BUILD_TAR=0|1 - Do (not) build the .tar.gz package
+#   BUILD_RPM=0|1 - Do (not) build the .rpm package
+#   BUILD_DEB=0|1 - Do (not) build the .deb package
+# All of these env vars are true by default.  If, for example, you just want
+# to build the branch as-is: CHECK=0 UPDATE=0 build-packages VERSION
+# Otherwise, this script is pretty strict and tries to ensure a good build.
+#
+# A few more things you should know:
+#  * You'll need rpmbuild and dpkg-buildpackage to build the rpm and deb pkgs
+#  * Output (STDOUT and STDERR) for some stuff is saved to files in tmpdir
+#  * All dates/times are UTC
+#  * No pkgs are signed (TODO)
