Tool to create Scheme virtual environments

## Installation

    make
    make install


## Usage

    scheme-venv chibi r7rs venv

Note that scheme-venv does not install snow-chibi, akku or any Scheme
implementations. You have to install them yourself into your system.

### bin/activate

First argument is Scheme, second is RnRS and third is path to directory. The
directory must not exist.

After the virtual environment is created you can activate is with:

    source venv/bin/activate


After activation you can install packages with either snow-chibi or akku and
they will be installed inside the virtual environment.

### bin/snow-chibi

Install R7RS package from [snow-fort.org](https://snow-fort.org).

### bin/akku

Install R6RS package from [akkuscm.org](https://akkuscm.org).

### bin/scheme-script

Run Scheme script.

### bin/scheme-compile

Compile Scheme code to executable.
