-//
-// The original intention was that ClFlags would be the core set of flags for a
-// release build, while ClFlagsExtra had optional flags that would be locked to
-// default values in a release build.  However, the division has evolved to be
-// fairly arbitrary.
-//
-// The variable flags in a release (browser) build should be limited to opt
-// level, number of threads, output file, and perhaps input file.
-//
-// The core flags should remain part of the GlobalContext object, but the
-// optional flags might as well be global, i.e. static members of GlobalContext,
-// so that they are easily accessed from anywhere without needing to plumb in
-// the GlobalContext object.
