# Because error messages were defined within Ecto, we must

# in the errors.po file.
# Ecto will pass the :count keyword if the error message is
# meant to be pluralized.
# On your own code and templates, depending on whether you
# need the message to be pluralized or not, this could be
# written simply as:
#
# dngettext "errors", "1 file", "%{count} files", count
# dgettext "errors", "is invalid"
