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.

be updated as expected.
If a dependency has a glide.yaml file, update will read that file and
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.
Glide will also import Godep, GB, and GPM files as it finds them in dependencies.
It will create a glide.yaml file from the Godeps data, and then update. This
has no effect if '--no-recursive' is set.
If the '--update-vendored' flag (aliased to '-u') is present vendored
dependencies, stored in your projects VCS repository, will be updated. This
works by removing the old package, checking out an the repo and setting the
version, and removing the VCS directory.
By default, packages that are discovered are considered transient, and are
not stored in the glide.yaml file. The --file=NAME.yaml flag allows you
to save the discovered dependencies to a YAML file.
