sets it up. It generates a glide.yaml file, parsing your codebase to guess
the dependencies to include. Once this step is done you may edit the
glide.yaml file to update imported dependency properties such as the version
or version range to include.
To fetch the dependencies you may run 'glide install'.`,

to the glide.yaml file. Multiple package names can be specified on one line.
$ glide get github.com/Masterminds/cookoo/web
The above will install the project github.com/Masterminds/cookoo and add
the subpackage 'web'.
If a fetched dependency has a glide.yaml file, configuration from Godep,
GPM, or GB Glide that configuration will be used to find the dependencies
and versions to fetch. If those are not available the dependent packages will
be fetched as either a version specified elsewhere or the latest version.
When adding a new dependency Glide will perform an update to work out the
the versions to use from the dependency tree. This will generate an updated
glide.lock file with specific locked versions to use.
If you are storing the outside dependencies in your version control system
(VCS), also known as vendoring, there are a few flags that may be useful.
The '--update-vendored' flag will cause Glide to update packages when VCS
information is unavailable. This can be used with the '--strip-vcs' flag which
will strip VCS data found in the vendor directory. This is useful for
removing VCS data from transitive dependencies and initial setups. The
'--strip-vendor' flag will remove any nested 'vendor' folders and
'Godeps/_workspace' folders after an update (along with undoing any Godep
import rewriting). Note, The Godeps specific functionality is deprecated and
will be removed when most Godeps users have migrated to using the vendor
folder.`,

update those dependencies accordingly. Those dependencies are maintained in
a the top level 'vendor/' directory. 'vendor/foo/bar' will have its
dependencies stored in 'vendor/'. This behavior can be disabled with
'--no-recursive'. When this behavior is skipped a glide.lock file is not
generated because the full dependency tree cannot be known.
