28## find: warning: ‘-name’ matches against basenames only, but the given pattern
29## contains a directory separator (‘/’), thus the expression will evaluate to
30## false all the time. Did you mean ‘-wholename’?
31##
32## [TODO] find and fix plugin script, change --name to --path:
33## find ! -name "*/docs/*"
34## ---------------------------------------------------------------------------
35## [TODO] see license/include.mk, grep -L will ignore binaries so no need to
36## explicitly filter images, spreadsheets, etc. Files containing utf-8 are
37## the only question mark.
