# Everything that is not comment, markup, doctype/shebang, or an empty line,
# is considered to be code.

# For example,
# * HTML files not containing JavaScript have 0 LoC
# * in a Java class without comments, LoC is the number of non-empty lines
#
# A Scanner class should define the token kinds that are not code in the
# KINDS_NOT_LOC constant, which defaults to [:comment, :doctype].
