 // A MultiProcessTest is a test class which makes it easier to
 // write a test which requires code running out of process.
 //
 // To create a multiprocess test simply follow these steps:
 //
 // 1) Derive your test from MultiProcessTest.
 // 2) Modify your mainline so that if it sees the
 //    kRunClientProcess switch, it will deal with it.
 // 3) Create a mainline function for the child processes
 // 4) Call SpawnChild("foo"), where "foo" is the name of
 //    the function you wish to run in the child processes.
-// 5) On posix, add the function's name to the list in the file
+// 5) On Linux, add the function's name to the list in the file
 //    base_unittests_exported_symbols.version
 // That's it!
