+================================================
+Environment Variables Impacting the Build System
+================================================
+
+Various environment variables have an impact on the behavior of the
+build system. This document attempts to document them.
+
+AUTOCLOBBER
+ If defines, the build system will automatically clobber as needed.
+ The default behavior is to print a message and error out when a
+ clobber is needed.
+
+ This variable is typically defined in a :ref:`mozconfig <mozconfig>`
+ file via ``mk_add_options``.
+
+REBUILD_CHECK
+ If defined, the build system will print information about why
+ certain files were rebuilt.
+
+ This feature is disabled by default because it makes the build slower.
+
+MACH_NO_TERMINAL_FOOTER
+ If defined, the terminal footer displayed when building with mach in
+ a TTY is disabled.
+
+MACH_NO_WRITE_TIMES
+ If defined, mach commands will not prefix output lines with the
+ elapsed time since program start. This option is equivalent to
+ passing ``--log-no-times`` to mach.
