Name: "update",
UsageLine: "update [-all] import",
Short: "update a local dependency",
Long: `gb vendor update will replaces the source with the latest available from the head of the master branch.
Updating from one copy of a dependency to another comes with several restrictions.
The first is you can only update to the head of the branch your dependency was vendered from, switching branches is not supported.
The second restriction is if you have used -tag or -revision while vendoring a dependency, your dependency is "headless"
(to borrow a term from git) and cannot be updated.
To update across branches, or from one tag/revision to another, you must first use gb vendor delete to remove the dependency, then
gb vendor fetch [-tag | -revision | -branch ] [-precaire] to replace it.
Flags:
-all
will update all dependencies in the manifest, otherwise only the dependency supplied.
-precaire
allow the use of insecure protocols.
