 Compiler Command-Line Syntax (http://msdn.microsoft.com/en-
 us/library/610ecb4h(v=vs.100).aspx)
   {{{CL [option...] file... [option | file]... [lib...] [@command-file]
 [/link link-opt...]}}}
   {{{option}}} - One or more CL options. Note that all options apply to
 all specified source files. Options are specified by either a forward
 slash (/) or a dash (–). If an option takes an argument, the option's
 description documents whether a space is allowed between the option and
 the arguments. Option names (except for the /HELP option) are case
 sensitive. See Order of CL Options for more information.

 Yes, I am.
