// Glide is a command line utility that manages Go project dependencies and
// your GOPATH.
//
// Dependencies are managed via a glide.yaml in the root of a project. The yaml
//
// Params:
// 	- filename (string): The name of the glide YAML file. Default is glide.yaml.
// 	- project (string): The name of the project. Default is 'main'.
// file lets you specify projects, versions (tags, branches, or references),
// and even alias one location in as other one. Aliasing is useful when supporting
// forks without needing to rewrite the imports in a codebase.
//
// A glide.yaml file looks like:
//
//		package: github.com/Masterminds/glide
//		imports:
//			- package: github.com/Masterminds/cookoo
//			  vcs: git
//			  ref: 1.1.0
//			  subpackages: **
//			- package: github.com/kylelemons/go-gypsy
//			  subpackages: yaml
//
// Glide puts dependencies in a vendor directory. Go utilities require this to
// be in your GOPATH. Glide makes this easy. Use the `glide in` command to enter
// a shell (your default) with the GOPATH set to the projects vendor directory.
// To leave this shell simply exit it.
//
// If your .bashrc, .zshrc, or other startup shell sets your GOPATH you many need
// to optionally set it using something like:
//
//		if [ "" = "${GOPATH}" ]; then
//		  export GOPATH="/some/dir"
//		fi
//
// For more information use the `glide help` command or see https://github.com/Masterminds/glide
