# These variables are used to produce less output when running make with V=0 or
# with the --enable-silent-rules flag.
#
# For each compiler kind of file generated by a command during the building of
# Erlang/OTP, a variable named <command>_verbose should be defined and used as
# a command prefix. The generic gen_verbose variable is offered for
# miscellaneous operations like sed, cp or magical Perl incantations.
#
# A second variable V_<COMMAND> is also provided for major compilation tools
# like CC, ERLC or JAVAC.
# DEFAULT_VERBOSITY is set by the --enable-silent-rules configure flag.
