Tool to create Scheme virtual environments

## Installation

    make
    make install


## Usage

    scheme-venv chibi venv

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

First argument is Scheme implementation you want to use, second is path to
directory. The directory must not exist.


### bin/activate

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).

If you want to use R7RS libraries on R6RS you can first install them with
snow-chibi and then run "akku install".

### bin/scheme-script

Run Scheme script. The RnRS is deducted from fiel suffix, .sps or .scm.

### bin/scheme-compile

Compile Scheme code to executable. The RnRS is deducted from fiel suffix,
.sps or .scm.
