Vndr is simple vendoring tool, which is inspired by docker vendor script.
Vndr has no options.
For initiating you will need config vendor.conf with lines like:
# Import path | revision | Repository(optional)
github.com/example/example 03a4d9dcf2f92eae8e90ed42aa2656f63fdd0b14 https://github.com/LK4D4/example.git
Just set $GOPATH and run vndr in your repository with vendor.conf.
Also it's possible to vendor only one dependency after initial vendoring:
vndr github.com/example/example 03a4d9dcf2f92eae8e90ed42aa2656f63fdd0b14 https://github.com/LK4D4/example.git
or
vndr github.com/example/example
to take revision and repo from vendor.conf.
