Implementation of Unlambda, an esoteric programming language.
## Description
Description
-----------
The U6a project provides a bytecode compiler and a runtime system for the [Unlambda](http://www.madore.org/~david/programs/unlambda/) programming language.
The U6a project provides a bytecode compiler and a runtime system for the

To install U6a from source, see INSTALL.md.
Usage (See [**u6ac**(1)](man/u6ac.1) and [**u6a**(1)](man/u6a.1) man pages for details):
Usage (See the u6ac(1) and u6a(1) man pages for details):
```bash
# Compile an Unlambda source file into bytecode.
u6ac -o foo.unl.bc foo.unl
# Execute the bytecode file.
u6a foo.unl.bc
```
# Compile an Unlambda source file into bytecode.
u6ac -o foo.unl.bc foo.unl
# Execute the bytecode file.
u6a foo.unl.bc
## Future Plans
Future Plans
------------
* Interactive debugger: `u6adb`
* More compile-time optimizations
* More test cases
* LLVM backend for `u6ac`
* Interactive debugger: u6adb
* More compile-time optimizations
* More test cases
