# A macro to define a command that uses the BIF compiler to produce C++
# segments and Bro language declarations from a .bif file. The outputs
# are returned in BIF_OUTPUT_{CC,H,BRO}. By default, it runs bifcl in
# alternative mode (-a; suitable for standalone compilation). If
# an additional parameter "standard" is given, it runs it in standard mode
# for inclusion in NetVar.*. If an additional parameter "plugin" is given,
# it runs it in plugin mode (-p). In the latter case, one more argument
# is required with the plugin's name.
#
# The macro also creates a target that can be used to define depencencies on
# the generated files. The name of the target depends on the mode and includes
# a normalized path to the input bif to make it unique. The target is added
# automatically to bro_ALL_GENERATED_OUTPUTS.
