-"""NaCl gcc wrapper that presents glibc and newlib as a single
-toolchain.
-
-This wraps the newlib and glibc compilers and allows users
-to choose which one they really want by passed in --glibc
-or --newlib on the command line.
-
-We need this when using gyp to generator build files since
-gyp only support one target toolchain and one host toolchain
-(for now).
