-"  guru.vim -- Vim integration for the Go guru.
-"
-"  Load with (e.g.)  :source guru.vim
-"  Call with (e.g.)  :GoGuruDescribe
-"  while cursor or selection is over syntax of interest.
-"  Run :copen to show the quick-fix file.
-"
-" This is an absolutely rudimentary integration of the Go Guru into
-" Vim's quickfix mechanism and it needs a number of usability
-" improvements before it can be practically useful to Vim users.
-" Voluntary contributions welcomed!
-"
-" TODO(adonovan):
-" - reject buffers with no filename.
-" - hide all filenames in quickfix buffer.
-
-" Get the path to the Go guru executable.
