Get Cosmopolitan into releasable state A new rollup tool now exists for flattening out the headers in a way that works better for our purposes than cpp. A lot of the API clutter has been removed. APIs that aren't a sure thing in terms of general recommendation are now marked internal. There's now a smoke test for the amalgamation archive and gigantic header file. So we can now guarantee you can use this project on the easiest difficulty setting without the gigantic repository. A website is being created, which is currently a work in progress: https://justine.storage.googleapis.com/cosmopolitan/index.html 2020-11-25 16:19:00 +00:00			`#include "libc/runtime/symbols.internal.h"`

Make terminal ui binaries work well everywhere Here's some screenshots of an emulator tui program that was compiled on Linux, then scp'd it to Windows, Mac, and FreeBSD. https://justine.storage.googleapis.com/blinkenlights-cmdexe.png https://justine.storage.googleapis.com/blinkenlights-imac.png https://justine.storage.googleapis.com/blinkenlights-freebsd.png https://justine.storage.googleapis.com/blinkenlights-lisp.png How is this even possible that we have a nontrivial ui binary that just works on Mac, Windows, Linux, and BSD? Surely a first ever achievement. Fixed many bugs. Bootstrapped John McCarthy's metacircular evaluator on bare metal in half the size of Altair BASIC (about 2.5kb) and ran it in emulator for fun and profit. 2020-10-11 04:18:53 +00:00			`void ShowBacktrace(int, const struct StackFrame *);`
