comply with the licenses of the projects you are using

[dimbleby]

eg hashivim/vim-terraform has a license including this text

Permission to use, copy, modify, and/or distribute this software for any purpose with or without fee is hereby granted, provided that the above copyright notice and this permission notice appear in all copies.

(emphasis added)

That condition has not been followed. Please fix it.

I would guess that similar is true for many of the projects used here

terraform doesn't have licenses inside of its vim files, so there's an extra file to copy. Do you think copying LICENSE -> licenses/terraform would be a good solution?

Probably needs a wildcard on the name. Something like :%s,\vLICENSE(.*),cp & licenses/terraform\1 so LICENSE, LICENSES.txt, LICENSES_gpl.txt would be named foo, foo.txt, foo_gpl.txt?
