-This is a modern statically-linked GNU C2X toolchain.
+DESCRIPTION
 
-You have the freedom to obtain the original sources to these binaries,
-and build ones just like them, by visiting:
+  Cosmopolitan GCC
+  Prebuilt x86_64-linux binaries
+  An APE-friendly C/C++ compiler

+LICENSE
 
-The musl-cross-make tool also produces libraries and header files. We've
-only vendored the statically-linked executable files, since Cosmopolitan
-won't depend on GPL-licensed headers / runtime libraries.
+  GPLv3 and other licenses (see LICENSE.txt)
 
-We haven't made any modifications to the original software. The versions
-we chose are documented in $PKG/LICENSE.txt. Here's our Musl

-    switch linux kernel headers to 4.19.88 by default
-    
-    using slim headers-only version. this change is needed to support all
-    future versions of musl on 32-bit archs, since prior to 4.16 the
-    kernel headers had incompatibility with userspace time_t not matching
-    the kernel's old (32-bit) time_t. support for older headers will be
-    dropped entirely soon.
