Vagrant Setup

This tutorial guides you through creating your first Vagrant project.

We start with a generic Ubuntu VM, and use the Chef provisioning tool to:

• install packages for vim, git
• create user accounts, as specified in included JSON config files
• install specified user dotfiles (.bashrc, .vimrc, etc) from a git repository

Afterwards, we'll see how easy it is to package our newly provisioned VM

# Find the mails you want to compress in a single maildir.
#
#     Skip files that don't have ,S=<size> in the filename. 
#
# Compress the mails to tmp/
#
#     Update the compressed files' mtimes to be the same as they were in the original files (e.g. touch command)
