    19  Vendor resets the workspace's vendor directory to include all packages
    20  needed to build and test all the workspace's packages.

    23  The -v flag causes vendor to print the names of vendored
    24  modules and packages to standard error.

    26  The -e flag causes vendor to attempt to proceed despite errors
    27  encountered while loading packages.
    28  
    29  The -o flag causes vendor to create the vendor directory at the given
    30  path instead of "vendor". The go command can only use a vendor directory
    31  named "vendor" within the module root directory, so this flag is
    32  primarily useful for other tools.`,
