+QuickJS is a small and embeddable Javascript engine by Fabrice Bellard
+and Charlie Gordon. It supports the ES2020 specification including
+modules, asynchronous generators, proxies and BigInt.
+It optionally supports mathematical extensions such as big decimal
+floating point numbers (BigDecimal), big binary floating point numbers
+(BigFloat) and operator overloading.
+
+Main Features:
+* Small and easily embeddable: just a few C files, no external
+  dependency.
+* Fast interpreter with very low startup time
+* Almost complete ES2020 support including modules, asynchronous
+  generators and full Annex B support (legacy web compatibility).
+* Passes nearly 100% of the ECMAScript Test Suite tests when selecting
+  the ES2020 features.
+* Can compile Javascript sources to executables with no external
+  dependency.
+* Garbage collection using reference counting (to reduce memory usage
+  and have deterministic behavior) with cycle removal.
+* Mathematical extensions: BigDecimal, BigFloat, operator overloading,
+  bigint mode, math mode.
+* Command line interpreter with contextual colorization in JS.
+* Small built-in standard library with C library wrappers.
+
+NOTE:
+In order to adhere to Slackware standards the source is patched to:
+* change library paths in the compiler
+* build a shared library
+Since the default behaviour of the compiler is to output statically
+linked binaries, an aditional shared library is provided so that users
+may produce C files from Javascript source code
+(e.g.: qjsc -e in.js -o out.c), and then compile and link dynamically,
+e.g.:
+  cc -I /usr/include/quickjs out.c -o executable -lquickjs
+I believe this is the less intrussive set of changes to achieve those
+goals.
