# licensecheck.sh
# checks for copyright/license headers on files
# excludes filename extensions where this check isn't pertinent

# --strict
# --strict-dates
#    see https://github...

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