+# BUILD 'PROFILES' - this is the area to set up configurations of flags to be used by developers
+# It is above more hardware specific configurations so hardware limitations can override some options
+# in these profiles. These represent the only supported flag configurations, and should be the only thing
+# passed on the command line in most scenarios.
+
+# Every profile should explicitly specify every option used by every other profile, with the exception of the
+# profile modifiers
+
+# The base profiles are fast, opt and debug - these reflect the output directories artifacts will get placed into
+# and match the bazel compilation modes
+
+# Should a profile modify another profile, it should be named {original_profile}_{modifier_name} - example fast_static
+
+# Current Profiles:
+# fastbuild
+# dbg
+# dbg_san
+# dbg_tsan
+# opt
