Project description
- …chews through your system dependencies, spitting out incompatible
versions.

Overview
When onboarding new team members, ensuring their computer has everything needed to work on the project can be painful. Verchew is a command-line program and embeddable Python script to check the versions of your project’s system dependencies. Its only external dependency is any Python interpreter, which should already be installed on macOS and most Linux-based operating systems.
Setup
Requirements
Python 2.7+ or Python 3.3+
Installation
Install verchew with pip:
$ pip install verchewor directly from the source code:
$ git clone https://github.com/jacebrowning/verchew.git
$ cd verchew
$ python setup.py installor embedded the script in your project using this guide.
Usage
Create a configuration file (.verchew.ini) containing your project’s system dependencies:
[Working Program]
cli = working-program
version = 1.2.
[Newer Working Program]
cli = working-program
version = 4.
message = Version 4 is required to get the special features
[Broken Program]
cli = broken-program
version = 1.2.3
[Optional Missing Program]
cli = missing-program
version = 1.2.3
optional = true
[Missing Program]
cli = missing-program
version = 1.2.3Run verchew to see if you have the expected versions installed:
$ verchew
